The invention provides a thermoplastic resin composition, a molded article, and production methods therefor. The thermoplastic resin composition can sufficiently exhibit a cellulose addition effect and impart excellent mechanical strength to the molded article, particularly a foam molded article. More specifically, the invention provides a resin composition and a foam molded article thereof. The resin composition contains: a cellulose fiber (A); an amorphous resin (B) having a glass transition temperature of 160° C. or lower; a crystalline resin (C) having a melting point (melting peak temperature) of 80° C. to 150° C. and a melting start temperature lower than the melting point by 30° C. or more; and a thermoplastic resin (D) having a melting point or a glass transition temperature higher than the melting point of the crystalline resin (C) by 5° C. or more.

RESIN COMPOSITION, AND FILM AND MULTILAYER STRUCTURE USING THE SAME

The present disclosure provides a resin composition containing a bio-polyethylene resin (A), an ethylene-vinyl alcohol copolymer (B), and an alkali metal salt (C), wherein the content of the alkali metal salt (C) is 10 ppm to 1500 ppm, in terms of metal, with respect to the weight of the ethylene-vinyl alcohol copolymer (B). With this resin composition, gel formation and a reduction in transparency during molding are suppressed, and a molded product having an excellent appearance can thus be obtained.

RUBBER TIRE COMPOUND CONTAINING IPN-PROMOTING RESIN

A vulcanizable rubber composition comprises an interpenetrating or ionic network (IPN)-promoting resin. The resin comprises side chain functional groups along the resin backbone, which, in the presence of an additive material, form the connections that make up the IPN. In one embodiment, such material is ZnO. A method for forming the rubber composition comprises, in a productive step, mixing the product of the non-productive step, the zinc oxide, and a resin derived from maleic anhydride. The zinc oxide and the resin are simultaneously added to the composition during the productive mixing stage. The rubber composition can be cured and incorporated in a tire component, such as, a tread.
