Abstract: A method of making a polypropylene product for use in making films and preferably biaxially oriented films and more preferably biaxially oriented films wherein a tenter-frame processing line is employed. The method includes the addition of low concentrations of a nucleating system in a mini-random polypropylene that allows for better processability and improved tensile properties. In one embodiment the nucleating system comprises a blend of a monocarboxylic acid nucleating agent and dicarboxylic acid nucleating agent. The nucleating system is combined with the polypropylene material and the resultant hot melt blend is further processed into biaxially oriented film. Alternately, the hot melt blend is formed into a convenient raw material for later use in a biaxial oriented film production facility. The resulting films possess superior processing and material characteristics.

Abstract: A specific combination of two different polyolefin clarifying and nucleating agents, namely 3,4-dimethyldibenzylidene sorbitol and p-methyldibenzylidene sorbitol is provided. Such a combination surprisingly provides improved clarification and crystallization temperatures to polypropylene articles and formulations, better than bis-p-methyldibenzylidene sorbitol alone and equivalent or better than 3,4-dimethyldibenzylidene sorbitol. Such a combination of compounds thus permits the utilization of a new additive for the purpose of modifying polyolefin properties, such as polypropylene clarification and nucleation. The inventive combination may be introduced within any polyolefin composition, again preferably polypropylene, which may then be molded into any shape or form. A method of producing a polyolefin plastic utilizing the inventive combination of compounds is also provided.

A curable composition comprising (A) an organopolysiloxane having functional groups capable of condensation reaction at both molecular terminals thereof and (B-2) a hydrophobic silica, wherein the hydrophobic silica (B-2) is thermally treated together with the organopolysiloxane (A). The organopolysiloxane (A) is preferably represented by the formula: W3nulla(R1a)Si(R2)Onull(Si(R2)O)nnullSi(R1a)W3nulla nullnullnull (wherein W represents a hydroxyl group or a hydrolyzable group; each of R1 and R independently represents an unsubstituted or substituted monovalent hydrocarbon group having 1 to 12 carbon atoms, provided that the hydrocarbon groups R1 as well as the hydrocarbon groups R may be identical with or different from each other; n is an integer of 5 or greater; and a is 0, 1 or 2). When, in the formula nullnullnull, W represents a hydroxyl group and a is 2, the curable composition preferably comprises, in addition to the components (A) and either (B-1) or (B-2), (C) an organosilane represented by the formula: R1bSiX4nullb nullInull (wherein R1 represents an unsubstituted or substituted monovalent hydrocarbon group having 1 to 8 carbon atoms; X represents a hydrolyzable group; and b is 0 or 1), or a partial hydrolyzate of the organosilane. Thus, a curable composition, especially a curable paint composition and an antifouling paint composition, and an antifouling coating film of the following characteristics can be provided. The curable composition, in particular when used as a coating material or a paint, is excellent in sprayability and enables forming a thick coating film by one-time application. The curable composition enables shortening the operating period for coating, and a coating film of uniform thickness can be obtained by the application thereof. The obtained coating film is excellent in film strength and film hardness and, when used for antifouling purposes, exerts excellent antifouling capability for a prolonged period of time. Further, the curable composition ensures excellent storage stability before application thereof.
