Abstract:
A process comprising:a) reacting, in the presence of a radical initiator,1) at least two comonomer units of the formulaCX.sub.2 CYAwhereinX is independently selected from H, Cl, or F;Y is H, Cl, F, O(CZ.sub.2).sub.n CZ.sub.3, (CZ.sub.2).sub.n CZ.sub.3, (OCZ.sub.2 CZ.sub.2).sub.n CZ.sub.3 or (O(CZ.sub.2).sub.n).sub.n CZ.sub.3 wherein n is from about 1 to about 12;Z is independently selected from H or F;A is H, Cl, or F;the first copolymer contains at least about 4 weight percent of each of the comonomer units;at least one of the said comonomer units contains a fluorine atom;under conditions sufficient to form a semicrystalline first copolymer;b) reacting, in the presence of said first copolymer, water, a radical initiator and at least one cure site provider, at least two comonomer units of the formula:CX.sub.2 CYBwhereinX and Y are as defined above;B is H, Cl, F or --OCOR wherein R is a linear or branched aliphatic hydrocarbon of from 1 to 20 carbons;at least one of said comonomer units contains a fluorine atom;under conditions sufficient to form a semi-crystalline polymeric composition.
