Title:
SATURATED HYDROCARBON POLYMER HAVING FUNCTIONAL GROUP AT END AND PROCESS FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2000/056784
Kind Code:
A1
Abstract:
Saturated hydrocarbon polymers having hydroxyl groups incorporated at the ends are useful as materials for highly weatherable urethanes. For producing these polymers, a multistage reaction has been necessary in which after completion of polymerization, the polymer ends are converted to olefinic ends and then subjected to hydroboration. A halogen-terminated hydrocarbon polymer obtained by cationic polymerization is reacted with a compound containing both a protected hydroxyl group as a substituent and an unsaturated bond to thereby easily obtain a saturated hydrocarbon polymer having the protected hydroxyl group at each end. This compound can be easily converted into a hydroxyl-terminated polymer by hydrolysis.
