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).

Abstract:
PROBLEM TO BE SOLVED: To provide polymer composites and a method for producing the polymer composites.SOLUTION: A set of microcapsules containing a phase change material is mixed with a dispersing polymer material to prepare a first blend. The dispersing polymer material has latent heat of 40 J/g at minimum and a transition temperature in a range of 0°C to 50°C. The first blend is processed to prepare a polymer composite. The polymer composite can be made into various forms such as a pellet, a fiber, a flake, a sheet, a film, a rod and the like. The polymer composite can be used as it is and can be incorporated into various articles in which heat adjustment characteristics are requested.
Abstract:
PROBLEM TO BE SOLVED: To provide a transparent gel composed of an easily synthesizable and purifiable silicone-containing resin, having excellent gel strength, transparency, oxygen permeability, refractive index, etc., and usable as a culture material for cells and organs, a container for preservation and an ophthalmic material, etc. SOLUTION: The transparent gel is composed of a copolymer containing a polysiloxane skeleton and a polycarbonate skeleton and a hydrophilic polymer produced by polymerizing a hydrophilic monomer and has an interpenetrating network structure of the copolymer and the hydrophilic polymer.
