Abstract:
The present invention relates to a transparent gel, which has an interpenetrating polymer network of a copolymer containing a polysiloxane structure and a polycarbonate structure and a hydrophilic polymer obtained by polymerizing a hydrophilic monomer. For more details, the present invention has an object to provide a transparent gel useful as a cultivation substrate, a container for storage and an ophthalmic material, comprising an easily synthesizable and purifiable silicone-containing resin, wherein a gel strength, transparency, oxygen permeability, birefringence and other characteristics are excellent.
Abstract:
PROBLEM TO BE SOLVED: To provide an aromatic PC resin composition excellent in fluidity and capable of giving moldings having a lowly anisotropic shrinkage and consequent improved dimensional stability and to provide a molding using the resin composition. SOLUTION: The aromatic PC resin composition comprises 100 pts.mass combined component comprising (A) 40 to 99 mass% aromatic PC resin or mixture of not less than 60 mass% aromatic PC resin with not more than 40 mass% fluidity improver and/or impact modifier and (B) 60 to 1 mass% silicic acid containing inorganic filler or mixture of not less than 35 mass% silicic acid-containing inorganic filler with not more than 65 mass% fibrous filler and (C) 0.05 to 3 pts.mass polyoxyalkylene alkyl ether group or polyoxyalkylene alkylaryl ether group-containing phosphoric mono- or di-ester represented by the formula: [R 1 -O-(C n H 2n O) m ] 3-x P(=O)-OH x (wherein R 1 is a 1 to 18C alkyl or a substituted phenyl group having a 1 to 18C alkyl group; n is 2 or 3; and x is 1 or 2). The molding comprising the resin composition is also provided. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a polymer having a sufficient molecular weight for satisfactory film strength, and a monomer combination suitable for obtaining a property inherent in wax. SOLUTION: The polymer comprises a copolymer of at least two monomers selected from the group consisting of (A) an acrylic acid ester/methacrylic acid ester, (B) an ethylenic unsaturated acid, for example, an acrylic acid, a methacrylic acid, and an itaconic acid, (C) a styrene or a styrene derivative, (D) a bifunctional or trifunctional ethylenic unsaturated compound, for example, divinylbenzen, glycol diacrylate, and TMP triacrylate; (E) a vinyl ether and (F) a polymeric wax ((F) is required to be contained in the copolymer in an amount of at least 1 wt.%).

Abstract:
PROBLEM TO BE SOLVED: To improve impact resistance and solve the problem of malappearance such as generation of iridescent luster or jetting without lowering the flowability of a polycarbonate resin/fatty acid polyester alloy. SOLUTION: The thermoplastic resin composition contains a resin mixture (A) comprising a 45 to 97 mass% polycarbonate resin (a-1) and a 55 to 3 mass% fatty acid polyester (a-2) and a 0.5 to 20 parts by mass of a rubber-like elastic body per 100 parts by mass of the resin mixture (A), wherein the component (B) is dispersed in the interface between the component (a-1) and the component (a-2) or in the domain of the component (a-2).
