Abstract: Acid-activated mercaptans are used as chain transfer agents in the copolymn. of acrylonitrile(I), giving high conversions to polymers with high nitrile content and good processability. Thus, 75 parts I and 25 parts Me acrylate were added to compn. contg. Na dioctyl sulfosuccinate 0.85, poly (vinylpyrrolidone) 0.30, water 205, nitrile rubber(added as latex) 9, and H3PO4 0.067 parts. The polymn. mixt. was heated to 54≦̸C, treated with 0.06 parts K2S2O8 and 1.2 parts pentaerythritol tetrakis(3-mercaptopropionate) and polymd. 3.5h, giving a polymer with av. mol. wt. 126,885 and Brabender torgue at 230≦̸ and 35 rpm 2/20m-g after 10 min

Abstract: Polymeric compositions having good impact resistance, low permeability to gases, and high-softening temperatures which are composed of a conjugated diene monomer, such as butadiene, an olefinically unsaturated nitrile, such as acrylonitrile, and indene are described.
