摘要:
Macromonomers of the formula I are described:Q-B(L-B).sub.n T (I)wherein n is at least 1.0;Q is a polymerizable group;B may be the same or different and is a difunctional block of molecular weight in the range of from 100 to 4000 and wherein at least one B is a perfluorinated polyether of formula II;--OCH.sub.2 CF.sub.2 O(CF.sub.2 CF.sub.2 O).sub.x (CF.sub.2 O).sub.y CF.sub.2 CH.sub.2 O-- (II)wherein the CF.sub.2 CF.sub.2 O and CF.sub.2 O 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 perfluorinated polyether is in the range of from 242 to 4,000;L is a difunctional linking group; andT is a terminal group.These macromonomers may be used in the production of contact lenses, corneal implants, cell growth substrate or medical implant.
