    Abstract: Acrylonitrile-indene copolymer(I) and acrylonitrile-coumarone copolymer contg. 50-90% acrylonitrile(II) having thermoplastic properties and can be readily thermoformed into containers with high heat-distorsion temp. (Td), low permeability to gas and exccllent resistance to solvents. Thus, I was prepd. 86% yield by stirring the mixt. of water 300, GAFAC RE-610 (emulsifier) 3, II 70, indene 30, n-dodecyl mercaptan 0.2 and K persulfate 0.3 wt. parts at 70OC for 16hr in N2 stream.

    Abstract: Graft acrylonitrile-butadiene-indene polymer, having good impact resistance, low permeability to gases, and high softening temp., was prepd. by grafting acrylonitrile and indene on nitrile rubber. Thus, an aq. emulsion of acrylonitrile 70, indene 17.5 and rubber latex 15 parts was polymd. at 60≦̸C for 6hr using K2S2O8 as catalyst and limonene dimercaptane, and then the reaction mixt. was heated to 70≦̸C and K2S2O8 0.2, indene 12.5 and limonene dimercaptane 0.5 part were added over a period 5hr to give I.

    Abstract: 1360685 Graft polymers STANDARD OIL CO 21 Oct 1971 [13 Nov 1970] 48958/71 Heading C3G A graft polymer is produced by polymerization of (A) from 70 to 85% by weight of an olefinically unsaturated nitrile, (B) 2 to 13% of an alpha-olefin of structure wherein R 1 and R 11 are C 1 to C 7 -alkyl groups, (C) 2 to 30% of a monomer selected from a vinyl ester, acrylate ester, an acrylamide or a methacrylate ester, and (D) up to 17% of a vinyl or vinylidene aromatic monomer, wherein the combined amount of (A)+(B)+(C)+(D) is 100%, in the presence of from 1 to 30 parts by weight per 100 parts of (A) + (B) + (C)+(D) of (E) a rubbery polymer of 50 to 100% by weight of polymerized conjugated diene monomer and 50 to 0% of a polymerized vinyl or vinylidene aromatic monomer. In the examples, graft polymers are prepared in aqueous emulsion from (a) butadiene-styrene rubber or polybutadiene, acrylonitrile, isobutylene, styrene and methyl acrylate, N-t-octyl acrylamide, N-t-butyl acrylamide or vinyl acetate and (b) polybutadiene, acrylonitrile, diisobutylene, styrene and methyl acrylate.
