Abstract
The physical properties of poly(fluoroalkoxyphosphazene) materials are improved by the addition of fluoroalkoxyphosphazene oils to said materials.
Claims6
A composition comprising at least one poly(fluoroalkoxyphosphazene) polymer having a molecular weight between about 3 .times. 10.sup.4 and 3 .times. 10.sup.6 and at least one lower molecular weight polyphosphazene oil having a molecular weight up to about 4 .times. 10.sup.3 and represented by the formula ##EQU3## in which n represents an integer from 3 to 100 and R.sub.F and R'.sub.F each represent a monovalent radical represented by the formula --(CH.sub.2).sub.m (CF.sub.2).sub.q CF.sub.2 Z, in which m is an integer of from 1 to 10, and q is an integer from 1 to 20, and Z is selected from the group consisting of F and H, the amount of said oil being between 2 and 50 parts by weight per hundred parts by weight of said polymer.
