The film is produced by diluting a master batch, which has been prepared in advance and is composed of the poly(arylene sulfide) and styrene-based resin, with an additional supply of the poly(arylene sulfide) so as to prepare a resin composition containing the polystyrene-based resin in an amount of 2-25 parts by weight per 100 parts by weight of the poly(arylene sulfide), and then biaxially stretching the thus-prepared resin composition.

Abstract: A polyarylene sulfide resin composition comprising a composition obtainable by a reaction of a polymer composition comprising(A) 100 parts by weight of a polyarylene sulfide resin,(B) 0.1 to 40 parts by weight of a monomer having one or more ethylenic unsaturated bonds and(C) 0 to 40 parts by weight of an unsaturated polyester. In the polyarylene sulfide resin composition of the present invention, a polymer produced by polymerization of the monomer or the monomer and unsaturated polyester, as compared with a resin composition wherein said polymer is simply blended, is in a state wherein it is uniformly mixed with the polyarylene sulfide resin and if necessary a filler. In other words, said polymer is uniformly dispersed in and mixed with the polyarylene sulfide resin to such a degree that the composition shows no phase separation even if it is passed through molding processes such as extrusion molding, injection molding, etc. carried out under normal conditions.

The latex is a random polymer comprising from about 65 to about 85 weight percent of at least one C.sub.4 -C.sub.6 conjugated diolefin and from about 15 to about 35 weight percent of styrene. The latex polymer is highly compatible with the asphalt cement without sacrificing many of the other desirable physical properties.

Since the polyarylene sulfide resin composition of the present invention is in a state wherein the polyarylene sulfide resin and thermoplastic polyester are uniformly mixed, the constituent components are uniformly dispersed and mixed to such a degree that the composition shows no phase separation even if it is passed through molding processes such as extrusion molding, injection molding, etc. carried out under normal conditions.

Abstract: Block copolymers of vinyl monomers and thioarylene segments are prepared from copoly(arylene sulfide-disulfides), i.e., copoly(arylene sulfides) having an appreciable quantity of disulfide linkages in the polymer chains. Such copoly(arylene sulfides) correspond to the structure [(--A--S--).sub.1-x (A--S--S--).sub.x ].sub.n, wherein X is in the range of 0.5 to 0.001 based on the combined number of (--A--S--) and (A--S--S--) units. In a preferred embodiment n is at least 200; however, polymers and prepolymers having a much lower degree of polymerization can be used, e.g., materials where n is about 25 or higher. To prepare the block copolymers, an unsaturated monomer capable of undergoing free radical addition polymerization under the reaction conditions employed is subjected to such polymerization in the presence of the copoly(arylene sulfide-disulfide) having the above formula. During the course of the polymerization, chain transfer occurs resulting in formation of the block copolymers.

Abstract: An aromatic composition comprises aromatic substances that are encapsulated and/or clathrated in a matrix of polymer. The polymer includes an inorganic polymer produced from metal alkoxides; a conjugated polymer produced from metal alkoxides and silane coupling agents; and a conjugated polymer produced from metal alkoxides, silane coupling agents, and organic monomers. The aromatic composition has slow-release characteristics, so that the aromatic substances are released over a long period of time. In a method for the production of the aromatic composition, a catalyst for sol-gel methods that comprises an acid or its anhydride and an organic base, and if necessary, irradiation with ultraviolet light and/or an electron beam are used for making the polymer.
