PROCESS FOR MAKING HIGH NITRILE MULTIPOLYMER PREPARED FROM ACRYLONITRILE AND OLEFINICALLY UNSATURATED MONOMERS

摘要

PROBLEM TO BE SOLVED: To provide a homogeneous acrylonitrile olefinically unsaturated multipolymer and a process to make the same. SOLUTION: A process for polymerizing an acrylonitrile monomer and one or more olefinically unsaturated monomers to prepare an acrylonitrile olefinically unsaturated multipolymer comprises the steps of: heating an initial multimonomer mixture comprising acrylonitrile monomer and one or more olefinically unsaturated monomer, under an inert atmosphere, in the temperature range of about 30°C to about 120°C; adding an initiator to the initial multimonomer mixture to start a polymerization reaction; adding a multimonomer feed mixture comprising acrylonitrile monomer and olefinically unsaturated monomer(s) to the polymerization mixture; and preparing a homogeneous acrylonitrile olefinically unsaturated multipolymer product.
