Abstract
PURPOSE: To produce a nitrile resin having excellent solvent resistance, by carrying out the polymerization by adding a proper amount of an unsaturated nitrile at an early stage of the polymerization, in polymerizing the unsaturated nitrile in the presence of a rubber latex.
CONSTITUTION: In the graft polymerization by adding 95W80pts.wt. monomer mixture consisting of 50W85wt% unsaturated nitrile, e.g., acrylonitrile, 50W5wt% vinyl compound, e.g., styrene, and 0W40wt% alkyl (meth)acrylate, e.g., methyl methacrylate, to 5W20pts.wt. (as solids) rubber latex, 1,3-conjugated diene content ≥50wt%; 15W30pts.wt. unsaturated nitrile, 0W5pts.wt. aromatic vinyl compound and 0W5pts.wt. alkyl (meth)acrylate are added and polymerized at an early stage of the polymerization; then, the remaining portions of the monomers are added in turn to continue the polymerization.
