摘要

Fluorine-containing polyols obtained by the free radical addition of a fluoro-olefin having the general formula: <IMAGE> (1) wherein Y represents F and Z represents Cl or F(CF2)n-wherein n is an integer from 0 to 10 or Y and Z together form a -(CF2)m- chain wherein m represents an integer from 2 to 4 to a polyol wherein each hydroxyl group is directly attached to a group of the formula: -(CH2)pO-(2) wherein p is an integer of at least 4.
