PCT No. PCT/EP96/01257 Sec. 371 Date Jan. 26, 1998 Sec. 102(e) Date Jan. 26, 1998 PCT Filed Mar. 22, 1996 PCT Pub. No. WO96/31546 PCT Pub. Date Oct. 10, 1996A macromer of formula (I) is described: Q-(PFPE-L)n-1-PFPE-Q, wherein n>1.0; PFPE may be the same or different and is a perfluorinated polyether of formula (II): -OCH2CF2O(CF2CF2O)x(CF2O)yCF2CH2O-, 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 PFPE is in the range of from 242 to 4,000; L is a difunctional linking group; and Q may be the same or different and is a polymerizable group. The macromer may be used preferably in the production of contact lenses. |
