STAR MACROMONOMERS AND POLYMERIC MATERIALS AND MEDICAL DEVICES COMPRISING SAME

摘要

A star macromonomer comprises multiple side chains attached to a nucleus, each side chain having at least a segment comprising hydrophobic units and at least a segment comprising hydrophilic units. Polymeric materials having improved oxygen permeability and water and ion transport rates are produced by polymerizing compositions comprising such a star macromonomer. Such polymeric materials are desirable for producing medical devices, such as ophthalmic devices.
