Polysciences is a specialty chemical manufacturer recognized for polymer reagents developed for research, development, and laboratory applications across Life Sciences, biomedical research, electronics, and environmental testing. Its polymer portfolio emphasizes controlled molecular properties and batch consistency to support reproducible laboratory results. Polysciences polymer reagents include block copolymers, biodegradable polymers, water soluble polymers, and functional materials such as amine functional polymers, hydroxyl functional polymers, acid terminated, and ester terminated systems.Â
These polymer reagents are widely used in drug delivery systems, tissue engineering scaffolds, hydrogel networks, PEG hydrogels, and resorbable medical device research, where properties such as enzymatic degradation, surface erosion, and bulk erosion influence performance. Polymer systems based on hydrophobic PCL, hydrophilic PEG, poly (lactic acid), poly (trimethylene carbonate), and PAMAM dendrimers support formulation chemistry, transfection reagents, microspheres and particles, and surface functionalization. In analytical workflows, these materials are applied in electron microscopy, flow cytometers, cell analyzers, immunoassays, and environmental testing.Â
Polysciences polymer reagents also support advanced material applications in electronic packaging materials, conformal coatings, wafer polishing, CMP slurries, post-CMP cleaners, and instrument standards. Custom synthesis, route development, tailored materials, and contract manufacturing enable alignment of polymer chemistry with defined research requirements, including intrinsic viscosity targets.Â
Through MSE Supplies, laboratories can reliably source Polysciences polymer reagents and laboratory products, ensuring dependable access for scientific research, surface functionalization, and advanced materials development.Â
What to know before you buy
This page lists polymerization products and biodegradable polymers from Polysciences, Inc. for controlled drug release, tissue engineering and medical device research. Most are lactide, glycolide and caprolactone based polymers sold as research powders or resins.
The core of the range is PLGA, poly(D,L-lactide-co-glycolide), in lactide to glycolide ratios of 50:50, 55:45, 65:35, 75:25 and 85:15. Each is listed by inherent viscosity (IV), from 0.2 to 1.1 dL/g, and by end group: acid, ester or glucose terminated. For example, the Polysciences PLGA 50:50, IV 0.7, acid terminated and the PLGA 85:15, IV 0.8, ester terminated sit at different points on degradation rate.
Other polymers include poly(L-lactide), polyglycolide, poly(trimethylene carbonate) and caprolactone copolymers such as poly(caprolactone-co-glycolide) 85:15 and poly(L-lactide-co-caprolactone) 70:30. Caprolactone-rich grades are softer and more elastic, which suits flexible scaffolds and films.
Frequently Asked Questions
How does the lactide to glycolide ratio affect PLGA?
Ratio changes how fast PLGA breaks down. Grades close to 50:50 tend to degrade fastest, while higher lactide content, such as PLGA 85:15, degrades more slowly and is more hydrophobic. Pick the ratio by how long your implant or particle needs to last.
What does inherent viscosity tell me?
Inherent viscosity tracks molecular weight. Low IV grades, such as 0.2 dL/g, have shorter chains, degrade faster and dissolve easily for microparticles. Higher IV grades, such as PLGA 75:25, IV 1.1, give stronger films, fibers and scaffolds and degrade more slowly.
Should I choose an acid or ester terminated PLGA?
Acid terminated PLGA has free carboxyl end groups, which make it more hydrophilic and speed up early degradation. It can also interact with basic drugs. Ester terminated PLGA is end-capped, more hydrophobic and degrades more slowly at first. The glucose terminated PLGA 55:45 is a specialty option.
When should I use caprolactone copolymers?
Caprolactone adds flexibility and slows degradation. Poly(caprolactone-co-L-lactide) 95:5 and the caprolactone-co-glycolide grades suit soft, elastic scaffolds, nerve guides and films. Poly(trimethylene carbonate) is another soft, elastic option.
Can I order Polysciences polymers in larger amounts or a grade not listed?
Yes. For larger quantities of a listed grade, use the bulk order request form. For other Polysciences ratios, viscosities or end groups, send your requirements through the quote request form.
