We manufacture and supply high quality block or graft copolymers made of PEG (PEO) and biodegradable polymers, natural polymers, or biopolymers. PEGWorks copolymers are uniquely designed and produced for drug delivery, drug formulation, drug solubility enhancement, controlled release, encapsulation, implants, tissue scaffolding, device coating, and materials formulations. PEGylated biopolymers include carbohydrates, hyaluronic acid, polyamino acid, PEI, polyester and others. Biodegradable polyesters including those made of caprolactones have been approved for clinical uses. We provide diblock (A-B) and triblock (A-B-A) copolymers of PEG with PLA (polylactic acid or polylactide), PLGA (polylactic acid-co-glycolic acid or polylactide-co-glycolide), and PCL (polycaprolactone). We also offer custom synthesis services for PEGylated copolymers with other biodegradable blocks of various molecular weights, and with functional groups.
