摘要:
An efficacy-indicating resin composition comprising a thermoplastic resin, an electron-acceptable organic compound having a volatility and a sparingly volatile electron-donative developable organic compound. The efficacy-indicating resin composition of the present invention has such many excellent characteristics that it is very simple in production, storage, use and the like, can be used in various shapes, and that its available period can optionally be determined in the range of periods of from several hours to several years. Further, it can enable a visual and easy discrimination of the available period.

Disclosed in this invention are the slow-releasing resin moldings which are the porous bodies obtained by stretching 1.1-10 times the resin compositions comprising 100 parts by weight of a thermoplastic resin, 50 to 400 parts by weight of a filler and an active ingredient in an amount not less than the saturation dissolution rate for the thermoplastic resin, and a process for producing such slow-releasing resin moldings.
摘要:
An antimicrobial substance contains as an active ingredient an ethylene copolymer comprising 40 to 95% by weight of ethylene, 5 to 60% by weight of at least one dialkylaminoalkylacrylamide comonomer represented by: wherein R₁ represents hydrogen or methyl; R₂ and R₃, each represents C1-4 alkyl and n is 2, 3, 4 or 5 and optionally up to 20% by weight of one or more other ethylenically unsaturated comonomers (e.g. methyl acrylate), and has a number average molecular weight of from 5,000 to 50,000. A biocidal metal ion (e.g. Ag, Cu, Zn) can be admixed in up to 5% by weight. The copolymer can be used as an aquous dispersion or as a molded product, or in amount of 0.1 to 50 parts per 100 parts of another thermoplastic polymer (e.g. a polyolefin, chlorine-containing polymer, polyester or polyamide). The substance is effective in controlling numerous phytopathogens and other industrially harmful bacteria and fungi and can be incorporated in various preparations and products.
