    Abstract: A process for preparing thermoplastic olefin elastomers which comprises mixing and extruding in a screw extruder (A) an olefin rubber having a number average molecular weight of about 10,000 to 100,000 and composed of a copolymer of ethylene with an .alpha.-olefin containing at least 3 carbon atoms and (B) about 1 to 15 parts by weight, per 100 parts by weight of the olefin rubber (A)? of a specified dicarboxylic acid monomer at about 200 to 320.degree.C in the presence of (C) 0.02 to 3 miliequivalents, per 100 grams of the olefin rubber (A), of an alkyl peroxide, and in the absence of molecular oxygen. The thermoplastic olefin elastomers have superior mechanical properties, thermal stability, processability and adhesiveness, and find a wide range of applications, for example, as extrusion or injection molding materials, adhesives, coating agents, and modifiers for plastics and rubbers.

    Abstract: A chlorinated olefin polymer containing 15 to 35 wt % of chlorine is obtained by chlorinating an olefinic polymer containing propylene units and C4-6 alpha-olefin units in a specified proportion and having a crystallinity of 10 to 50 % and a limiting viscosity of 0.80 to 6.0 dl/g. This chlorinated olefin polymer is used as an adhesive upon laminating a chlorine-containing polymer such as polyvinylidene chloride or an aromatic polymer such as polystyrene on polyolefin, showing excellent adhesiveness in a high-temperature atmosphere.

    Abstract: This invention relates to a hot-melt adhesive composition comprising a styrene-type hydrocarbon-modified polyolefin composed of 100 parts by weight of a crystalline polyolefin having a degree of crystallinity of at least 10% and 0.15 to 50 parts by weight of a styrene-type hydrocarbon bound thereto by graft-copolymerization, said modified polyolefin having an intrinsic viscosity [ eta ] of 0.5 to 5 dl/g, a degree of crystallinity of at least 10% and a weight average molecular weight Mw/number average molecular weight Mn ratio of from 1 to 15. This invention also relates to the use of the hot-melt composition and to a laminated article comprising the holt-melt composition.
