摘要： Copolymers useful as contact lens materials are the polymerization product of a mixture comprising:(a) an itaconate;(b) a compound represented by formula (I): ##STR1## wherein: each A is independently an activated unsaturated radical;each R is independently selected from the group consisting of a C.sub.1 -C.sub.12 monovalent hydrocarbon radical, a C.sub.1 -C.sub.12 monovalent hydrocarbon radical containing ether linkages, a halogen-substituted C.sub.1 -C.sub.12 monovalent hydrocarbon radical, and a halogen-substituted C.sub.1 -C.sub.12 monovalent hydrocarbon radical containing ether linkages;each R' is independently a C.sub.1 -C.sub.22 divalent hydrocarbon radical; andn averages about 15 to about 50;(c) an ethylenically unsaturated organosiloxane monomer; and(d) a hydrophilic monomer.
