Abstract
A novel crosslinkable ambifunctional perfluorinated polyetheris provided wherein the polyether is defined by the formula X1—(CaF2aO)n—X2 where X1 and X2 are different functional terminal groups which are capable of forming a crosslinked perfluorinated polyether by addition, condensation or ring-opening reaction, and n ranges from 1 to 2000 and a is an integer of from 1 to 4. The mole ratio of X1 and X2 is 1:1. A release film may be formed from the cross-linked perfluorinated polyether.
Claims11
A method of production of a crosslinked perfluorinated polyether release film comprising the steps of:
- (a) providing a solvent-free coatable crosslinkable perfluorinated polyether, the polyether defined by the formula X1—(CaF2aO)n—X2, where X1 and X2 are different functional terminal groups which are capable of forming a polymer by addition, condensation or ring-opening reaction, n ranges from 1 to 2000 and a is an integer of from 1 to 4, and wherein the ratio of X1 and X2 is 1:1;
- (b) coating said polyether on a substrate;
- and
- (c) subjecting said coated polyether to a thermal or radiation source effective to crosslink said polyether.
