Abstract: A laminate consisting essentially of a layer of a thermoplastic resin (A) and a layer of a vinylidene fluoride resin (B), the layer of the resin (A) containing (C) polymerized units of an ethylenic unsaturated carboxylic acid ester in a proportion of 3 to 80% by weight based on the total weight of the layer of the resin (A). The polymerized units (C) of an ethylenic unsaturated carboxylic acid ester may exist either as a copolymer constituent of the resin (A) or in the form of an ethylenic unsaturated carboxylic acid ester polymer (C') blended in the layer of the resin (A).

Abstract: When the impact resistant resin composition comprising a graft polymer in which an aromatic alkenyl compound and an alkenyl cyanide compound are grafted on a rubbery polymer, and a matrix consisting essentially of an aromatic alkenyl compound-alkenyl cyanide compound copolymer satisfies the following conditions, the composition has an improved vacuum formability and the molded articles obtained by vacuum-forming the same have smaller variations in thickness at any given area and there is a smaller reduction of strength due to contact with foamed polyurethane:(1) the proportion of the rubbery polymer in said impact resistant resin composition is 10-30% by weight,(2) the graft polymer has a degree of grafting of 70-120% by weight,(3) the matrix has an intrinsic viscosity of 0.55-0.80 dl/g as measured at 30.degree. C. in methyl ethyl ketone, and(4) the weight ratio of the aromatic alkenyl compound to the alkenyl cyanide compound in the impact resistant resin composition is in the range of 2.0-2.8.

Abstract: A flame-retardant polymer composition comprising a flame-retardant polymer and a different kind of a polymer, the amount incorporated of the flame-retardant polymer being 2 to 50 percent by weight based on the different polymer and said flame-retardant polymer being prepared by copolymerizing 2 to 100 percent by weight of a monomer represented by the following general formula (A) ##SPC1##wherein R.sup.1 and R.sup.2 stand for H or CH.sub.3, R.sup.3 is a linear or branched alkylene group having 2 to 6 carbon atoms, which may be substituted by a hydroxyl group, X designates Br or Cl, n is a number of from 3 to 5, and m is a number of from 0 to 1,With 98 to 0 percent by weight of at least one unsaturated compound copolymerizable with the monomer (A).
