  • Polymer compositions
    Patent number: 4942203
    Abstract: A polymer composition comprising (1) a polyether polyol which is a product obtained by the free radical addition of a fluoro-olefin of the general formula: ##STR1## wherein Y represents F or fluoroalkyl and Z represents Cl or F(CF.sub.2)m--wherein m is an integer from 0 to 10 or Y and Z together form a (CH.sub.2)p--chain wherein p represents an integer from 2 to 4, to a polytetramethylene gylcol having a molecular weight in the range 162 to 5000 and (2) at least one acrylic polymer. The composition is useful for coating compositions or for the fabrication of films.
