We manufacture and supply high quality block or graft copolymers made of polyethylene glycol (PEG) or polyethylene oxide (PEO) and biodegradable polymers, natural polymers, or biopolymers under the brand name of PEGWorks. PEGWorks copolymers are uniquely designed and produced for drug delivery, drug formulation, device coating, and materials formulations.

PEGylated biopolymers include carbohydrates, hyaluronic acid, polyamino acid, PEI and others. PEGylated biodegradable polymers can be used for drug delivery with controlled release, microencapsulation, drug solubility enhancement and other biomedical applications including implants, tissue scaffolding, films 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 reactive functional groups.
