Abstract: 1521716 Aqueous dispersion of polymers based on non-tertiary allyl acrylates BASF AG 12 Dec 1975 [14 Dec 1974] 50975/75 Heading C3P A polymer made up of, by weight (a) 70- 90% of a non-tertiary C8 alkyl acrylate, (b) 4-12% of methyl methacrylate, (c) 4-12% of a vinyl ester of a C2-4 carboxylic acid, (d) 1- 5% of acrylonitrile, (e) 0À5-3% of a hydroxy C2-5 alkyl (meth)acrylate, and (f) 0À5-3% of an alpha,#-olefinically unsaturated mono- or di-carboxylic acid or a monoester of such a dicarboxylic acid, is prepared by conventional emulsion polymerization to a K value of 74 to 90 in aqueous medium containing as emulsifying agent a sulphated and alkoxylated fatty alcohol, fatty amine or alkyl phenol. Component (a) may also contain other non-tertiary alkyl acrylates whose homopolymers have glass temperatures below -30‹ C. and component (f) may also contain vinyl sulfonic acid or a salt thereof. Uses.- As pressure sensitive adhesives when coated on a suitable backing.

Abstract: Hot melt adhesives contg. (A) 50-80 parts mixt. of 80-98 parts of polyisobutylene (I) with mol. wt. (Stavdinger) of 10000-20000 and 20-2 parts polyisobutylene (II) of mol.wt. 100000-180000. (B) 10-35 parts thermoplastic rubbery block copolymer of styrene and a 1,3-diene, with Mn 80000-250000, and (C) 10 to 35 parts tackifying resin with softening pt. 60-120 degrees C. Also equipment for continuous prodn. and processing of such adhesives. Adhesive is used for coating of labels, insulating foils for building, corrosion-protective bandages, etc. The adhesives have good dimensional stability, and no uncontrolled breakdown of the rubber additive occurs during processing. They show esp. high cohesion, are suitable for continuous prodn., and avoid the pollution, explosion and other hazards of solvents-based adhesives.
