ABSTRACT:
The copolymers include a hydrophobic monomer and an acryloyl or methacryloyl ester of a propylene glycol monomethyl ether, also referred to as 1-methyl-2-methoxyethyl acrylate (“MMOEA”). The combination of the hydrophobic monomer and the MMOEA monomer advantageously provides desired mechanical strength, biocompatibility, and drug permeability in the copolymers. The copolymers can advantageously be used on medical devices.
