Product 1

HCID 1683252-Propenoic acid, 2-methyl-, methyl ester, polymer with ethenylbenzene and 2-propenenitrile

Procedure

To a separate reactor, 73.85% by weight of methylmethacrylate, 5% by weight of acrylonitrile, and 21.15% by weight of styrene are added and suspension polymerized. The resultant product is dehydrated and dried to obtain methylmethacrylate-acrylonitrile-styrene copolymer resin (MSAN) with a weight average molecular weight of about 105,000 in bead form.
