LOW-MOLAR-MASS POLYMERS COMPRISING AT LEAST ONE 4-METHYLETHER-1,3-DIOXOLAN-2-ONE END GROUP |
摘要 |
<p>A polymer of formula (I): in which P is a divalent polymeric radical other than a polyoxypropylene radical; m is a number from 1 to 6; B is a monovalent, divalent, trivalent, tetravalent, pentavalent or hexavalent radical, having from 1 to 44 carbon atoms per molecule; the divalent polymeric radical P being such that the number-average molar mass Mn of the polymer of formula (I) is in a range from 400 to 8000 g/mol and such that the polydispersity (Pd) of the polymer of formula (I) is within a range from 1.0 to 4.0. Process for preparing the polymer of formula (I). Process for preparing polyurethanes, by reaction of a polymer of formula (I) with a compound, having an amine group, and also polyurethanes that may be thus obtained.</p> |
