Microwave-dielectrometric monitoring of polymerization. Carlini, C.; Houben, H.; Martinelli, M.; Rolla, P. A. (Ist. Chim. Org. Ind., Univ. Pisa, Pisa, Italy).Several reagents with their cas registry numbers 88-12-0 and 13048-33-4 are used here. Pitture Vernici, 59(10), 45-7 (Italian) 1983. CODEN: PIVEAY. ISSN: 0048-4245. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) A method was proposed for studying the kinetics of thermal and photochem. homopolymn. of N,N-vinylpyrrolidine [88-12-0] and copolymn. with Bu acrylate [141-32-2] and 1,6-hexanediol diacrylate [13048-33-4] by measuring the dielec. const. (e) at microwave frequencies. A correlation was established between the e vs. time dependence and polymn. rate. The error in e measurement was ￡1% at frequency and temp. fluctuations 1-3 MHz and 0.5°, resp. .

Epoxy resin adhesives and primers

Epoxy resin adhesives and primers. (Yokohama Rubber Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58185671 A2 29 Oct 1983 Showa, 5 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C09J003-16; C08G059-14. APPLICATION: JP 82-68722 26 Apr 1982. DOCUMENT TYPE: Patent CA Section: 38 (Plastics Fabrication and Uses) Epoxy resin adhesives have good adhesive strength if they contain, or are applied over primers contg. dialkylaminoalkylamine-(meth)acrylate adducts (C1-3 alkyl groups). Thus, degreased and chromic acid-etched Al sheets were laminated with a compn. of Epikote 828 [25068-38-6] 70, Epikote 872 [39409-30-8] 30, m-xylenediamine 10, ATBN 1300 X16 (amino-terminated nitrile rubber) 10, and dimethylaminopropylamine-trimethylolpropanetriacrylate adduct (I) 2 parts and cured at room temp. 15625-89-5 and 13048-33-4 which are cas registry numbers of substances are two of reagents here. for 24 hs, then at 80° for 1 h. The resulting bonds had T peel strength 3.5 kg/in. (with cohesive failure), compared with 2.5 kg/in. (adhesive failure) using the same compn. without I. .
