Effect of the chemical structure of polyfunctional unsaturated compounds on radiational vulcanization of elastomers

Effect of the chemical structure of polyfunctional unsaturated compounds on radiational vulcanization of elastomers. Kolesnikov, A. A. (IvNIIPIK, USSR). Kozh.-Obuvn. Prom-st., (12), 40-1 (Russian) 1983. CODEN: KOOPAJ. ISSN: 0023-4354. DOCUMENT TYPE: Journal CA Section: 39 (Synthetic Elastomers and Natural Rubber) Section cross-reference(s): 38 Use of acrylates of polyhydric alcs. as vulcanizing agents in the radiochem. vulcanization of diene rubbers, e.g. 2274-11-5 and 4986-89-4 are also in the experiment., in manuf. of leather substitutes, decreased by 1.5-fold the optimal radiation dose and improved the physicomech. properties of the vulcanizates, but a deterioration in these properties was obsd. on increasing the functionality of the agents. Ethylene glycol diacrylate [2274-11-5], glycerol triacrylate [5459-38-1], and pentaerythritol tetraacrylate [4986-89-4] were used as the vulcanizing agents for EPDM, butadiene, and nitrile rubbers. .

Sheets for blister packaging

Sheets for blister packaging. (Tobi K. K.; Uchiyama, Hiroshi, Japan). Jpn. Kokai Tokkyo Koho JP 58168552 A2 4 Oct 1983 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: B32B015-08; B65D065-40; B65D075-26; B65D075-34; B65D083-04. APPLICATION: JP 82-54430 31 Mar 1982. DOCUMENT TYPE: Patent CA Section: 38 (Plastics Fabrication and Uses) Section cross-reference(s): 63 Moistureproof, air-impermeable sheets for blister packaging are prepd.Several substances with their cas registry numbers 15625-89-5 and 4986-89-4 may be metioned in this study. by vacuum-metalizing a thermoplastic resin film with Al on one side and then coating with a UV-curable coating material. Thus, a 30-m unoriented PVC [9002-86-2] film was vacuum-metalized with Al and then gravure-printed with a UV-curable coating material consisting of a urethane-modified acrylic oligomer 20, trimethylolpropane triacrylate [15625-89-5] 20, a triol 20, EtOAc 39.7, and benzophenone 0.1 part, which was cured by exposure to UV rays. The other surface of the film was gravure-printed with a mixt. of 40 parts vinyl chloride-vinyl acetate copolymer [9003-22-9] and 60 parts EtOAc and cured at 40-60° to give a sheet which was applied to a capsule-contg. blister-type container. The sheet easily broke along the blister portion so that the capsule was easily removed. .
