ABSTRACT:
Copolymeric macromonomers containing alkyl acrylate and methacrylate units and units of polysiloxanylalkyl esters of acrylic and/or methacrylic acids and a terminal carbon-carbon double bond organo group are useful for copolymerizing with other acrylate or methacrylate esters to make improved polymer compositions such as for contact lenses.
