CELL GROWTH SUBSTRATE POLYMER

摘要

Cell growth substrate polymers are described which comprise a macromonomer of the formula (I): Q -(PFPE - L)n-1 -PFPE-Q, wherein n is at least 1.0; each PFPE may be the same or different and is a perfluorinated polyether of the formula (II): -OCH2CF2O (CF2CF2O)x(CF2O)y CF2CH2O-, wherein the CF2CF2O and CF2O units may be randomly distributed or distributed as blocks throughout the chain and wherein x and y may be the same or different such that the molecular weight of the perfluoropolyether is in the range of from 242 to 4000, L is a difunctional linking group; and Q at each end of the macromonomer is the same or different and is a polymerizable group. The cell growth substrate polymers may be used in the production of corneal implants.
