About Us

ULTROXA Team

We Are Passionate. We Are Committed.

We focus our efforts into the design and production of high quality polymers to leverage the most out of the poly(2-oxazoline) platform. We strive to offer easy access of novel quality polymers both the academic and industrial research communities.


ULTROXA® is a spin-off project for contract development and manufacturing of poly(2-oxazoline)s and polyethyleneimines based in Ghent, Belgium.


ULTROXA®’s mission is to become the reference supplier of high-quality, high-purity well-defined poly(2-oxazoline)s. We strive to offer easy access of novel polymers to the research community.

We offer high quality polymers to customers in the biopharmaceutical industry and beyond. ULTROXA® is a spin-off of the research group of Professor Richard Hoogenboom from Ghent University.

ULTROXA®: Not only polymers. Beyond our product offer we provide you with key know-how to get the most out of the poly(2-oxazoline) platform preparing tailor-made polymers for your application.

A selection of ULTROXA® products is currently available in the SIGMA-ALDRICH® catalog. ULTROXA® products have also been made available in the Tokio Chemical Industry (TCI) catalog. More ULTROXA® products will be found via other distributors soon.

We are committed to providing the highest quality in the market. That’s why our QMS has been developed and implemented according to ISO 9001:2015 standard.


About  Ultroxa Polymers

ULTROXA® is a spin-off project of the research group of Professor Richard Hoogenboom at Ghent University, Belgium. The ULTROXA® spin-off is a research and manufacturing company committed to the development of a full range of ultra-defined poly(2-oxazoline)s and polyethyleneimines unique polymers for applications in therapeutics, drug formulation, nanomedicines, biomaterials and diagnostics. Beyond biomedicine, the unique versatility of the PAOx polymer platform enables its use in a wide range of areas spanning from cosmetics to smart materials and solar cells.

We have developed and patented a high-quality polymer production system. In addition, we have built a strong IP portfolio protecting key polymer compositions (learn more).

At ULTROXA®, we help you developing new innovative products by providing a scalable source of tailor-made polymers which best suit your needs.

ULTROXA® polyoxazolines

Our Mission

ULTROXA®’s mission is to become the reference supplier of high-quality, high-purity, well-defined poly(2-oxazoline)s. Much of the success of the current gold standard, polyethylene glycol (PEG), has been connected to its availability in the purity and definition required for its application in biomedicine. We strive to offer easy access of novel polymers to the research community, providing solutions unachievable with the current technology. We are committed to enable and support the development of poly(2-oxazoline)s applications in industry via design and production of tailor made products.

In all, ULTROXA® aspires to act as a catalyst in the development of new applications, boosting the poly(2-oxazoline) breakthrough in the market, with a special focus on biomedicine, where the PAOx/POZ technology enables solutions for unmet clinical needs with a strong societal impact.

Our Scientific Excellence

We offer high quality polymers to customers in the biopharmaceutical industry and beyond. Over 30 years of combined scientific excellence in the poly(2-oxazoline) field and our patent portfolio has enabled us to build a strong business case. ULTROXA® is a spin-off from the research group of Professor Richard Hoogenboom at Ghent University.

Prof. Hoogenboom was appointed as associate professor at Ghent University in 2010, when he initiated the Supramolecular Chemistry Group and in 2014 he was promoted to full professor. He has (co)authored over 300 scientific articles, more than 150 on poly(2-oxazoline)s, and his research accumulates over 11,000 citations (full publication list available here). Prof. Hoogenboom is a worldwide-recognized expert in the field of poly(2-oxazoline)s and is the co-founder and co-organizer of the biannual symposium on poly(2-oxazoline)s within the American Chemical Society (ACS) national meeting.

Prof. Hoogenboom’s work and the research conducted at his group have recently been recognized with the inaugural Polymer Chemistry Lectureship (2015), the fifth PI IUPAC award (2016) and the Ghent University Prometheus award for research (2016).

Ultroxa Services

ULTROXA®: Not only polymers. Beyond our product offer we provide you with key know-how to get the most out of the poly(2-oxazoline) platform, preparing tailor-made polymers for your application.

We are experts in preparing tailor-made polymers to help you create innovative products in a wide range of areas. We make sure that the polymer is optimized to the application you envision. With ULTROXA®, you assure a scalable supply of high-quality materials, and the confidence of having the support of a world-leading team of experts committed to help you succeed.

We have developed proprietary production methods to meet both the medical and the larger-scale non-medical industries, always providing the highest quality product for your application. ULTROXA® polymers have very narrow molar mass distributions (dispersity typically < 1.10), and high purity (> 95 %).

Besides offering our know-how and the source of the highest quality PAOx/POZ in the market, we offer you our robust and versatile functionalization technology, combined with the highest defined polymers available. Our proprietary technology is already the basis of highly effective hemostats and a disruptive new medical device, general adhesive tissue tape by GATT Technologies N.V.

Feel welcome to explore our product range and to contact us for more information.
