Abstract:
PROBLEM TO BE SOLVED: To provide a polylactic acid composition having excellent heat resistance and molding cycle properties. SOLUTION: The thermoplastic resin composition having the excellent heat resistance and molding cycle properties is produced as follows: Polylactic acid is compounded with a copolyester resin having a specific melting point together with a nucleating agent in order to improve the heat resistance of the polylactic acid and shorten the molding cycle. Thereby, the heat deformation resistance temperature can be improved and the molding cycle can further be shortened to that comparable to usual thermoplastic resins. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition using a recycled PET resin and improving impact resistance and extrusion processability which are considered as disadvantages thereof and to provide a molded product thereof. SOLUTION: The thermoplastic resin composition having the excellent impact resistance and good extrusion processability is obtained by mixing the recycled PET resin mainly of a bottle with a modified olefin resin having a functional group in a prescribed proportion and further adding a prescribed amount of a homopolymer of an unsaturated epoxy compound or a copolymer of the unsaturated epoxy compound with components composed of an aromatic vinyl compound and an ethylenically unsaturated compound. The molded product thereof is obtained. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a ring-shaped or a sheet-like mosquito-repellent article made of an elastomer, preventing evaporation of eucalyptus oil, providing good dispersion and having excellent control of mosquitoes. SOLUTION: The ring-shaped or the sheet-like mosquito-repellent article made of the elastomer and having excellent control of the mosquitoes is a safe and simple bracelet or sheet for control exhibiting excellent effects on the control of the mosquitoes and is formed by a method, wherein the eucalyptus oil is mixed with a certain limited elastomer and a dispersant is charged during injection molding to uniformly disperse the eucalyptus oil or porous silica impregnated with the eucalyptus oil, to thereby prepare a bracelet or a sheet.

Abstract:
PROBLEM TO BE SOLVED: To obtain a cell culture substrate which is industrially mass-produced, has durability and is inexpensively produced and to provide a method for producing the same. SOLUTION: The cell culture substrate has a surface modified layer on a substrate and has a constitution that the surface modified layer has a polymer containing an amino group (-NH 2 ) obtained by reacting a polymer represented by formula (II) (n and m are each a positive integer showing a polymerization degree; n may be 0 but m is not 0) formed by chemical vapor deposition of formyl[2,2]paracyclophane with a polymer containing an amino group capable of forming at least one Schiff's base on a monomer unit.
