PRODUCTION PROCESS OF MODIFIED POLYETHER POLYOLS AND THEIR USE IN PRODUCTION PROCESSES OF POLYURETHANE RESINS

摘要

The present invention relates to a process for the production of modified polyether polyols by the radical polymerization of a mixture of acrylonitrile, styrene, a salt of an alpha , beta -unsaturated monocarboxylic or polycarboxylic acid containing a primary, secondary or tertiary monoamine or polyamine and optionally copolymerizable compounds with a polyether polyol.
