    摘要: The present invention provides polylactic compositions effecting an excellent mold releasability upon processing and significantly improved elongation at break and impact strength without affecting the transparency. Also provided is a shrink film which decomposes under the natural environment and has excellent transparency, flexibility, shrinkability and mold releasability upon processing by applying the polylactic acid composition to a shrink film. There is provided a biodegradable polymer composition comprising 100 parts by weight of polylactic acid and 5 to 70 parts by weight of EVA. Further, a biodegradable polymer composition is provided comprising the polymer composition with one or more additives selected from the group consisting of 0.05 to 5 parts by weight of a lubricant, 1 to 50 parts by weight of plasticizer, 0.5 to 5 parts by weight of thermal stabilizer and 0.05 to 5 parts by weight of mold releasing agent. These biodegradable polymer compositions are applied to shrink films.

    摘要: The invention provides a novel method for surface priming when adhesive bonding is desired between a rubber, e.g. silicone rubber, and a substrate of a material such as a metal or plastic resin. The inventive method is performed by use of a primer composition of which the principal ingredient is an organosilicon polymer hitherto not used for such a purpose. The organosilicon polymer is represented by the average unit formula R.sub.a Six.sub.4-a, in which R is a monovalent hydrocarbon group, X is a divalent atom or group selected from the class consisting of an oxygen atom, an imino group, alkylene groups and a phenylene group and a is a positive number of 0.2 to 1.8, at least one of the hydrocarbon groups denoted by R in a molecule being aliphatically unsaturated and at least 10% by moles of the groups denoted by X in a molecule being the imino groups. This primer composition has good workability and gives adhesive bonding capable of withstanding a prolonged heat treatment in a dry condition or by dipping in a hot oil such as a silicone fluid.
