Polymers of [4-(methylether)-1,3-dioxolane-2-one of polyether polyol]

Abstract

The invention relates to a polymer of formula (I): in which R is a hydrogen or an alkyl having from 1 to 4 carbon atoms; m is a number from 1 to 6; B is a monovalent, divalent, trivalent, tetravalent, pentavalent or hexavalent radical comprising from 1 to 44 carbon atoms per molecule; and n is such that the number-average molar mass Mn of the polymer of formula (I) is from 4000 to 18 000 g/mol and its polydispersity (Pd) is within a range from 1.0 to 1.4. Process for the preparation of the polymer of formula (I). Process for the preparation of polyurethanes comprising the reaction of a polymer of formula (I) with a compound comprising an amine group, and also poly-urethanes capable of being thus obtained.
