Metal-platable polyester resin compositions. (Toray Industries, Inc., Japan). Jpn. Kokai Tokkyo Koho JP 59027946 A2 14 Feb 1984 Showa, 8 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08L067-02; C08K005-15. ICA: C08G059-42. ICI: C08L067-02, C08L063-00. APPLICATION: JP 82-136302 6 Aug 1982. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Section cross-reference(s): 56 Melt-extrudable polyester resin compns. having excellent mech. properties and adhesion to plated metal films comprise arom. polyester resins 100, aliph. polyester resins 1-100, and epoxides and/or glycidyl group-contg. olefin copolymers 0.01-80 parts. Thus, poly(butylene terephthalate) [24968-12-5] 100, poly(e-caprolactone) [24980-41-4] 10, and diglycidyl tetrahydrophthalate (I) [21544-03-6] 2.0 parts were mixed, pelletized in an extruder at 250° (90% of mixt. fed recovered as pellets), and injection molded into test plates, which were pretreated in solns. of NaOH, then HCl, then acidified with SnCl2, and acidified with PdCl2. The pretreated plates were washed and electroless plated with Cu, then electroplated first with Cu, then Ni, and then Cr to obtain metalized plates having metal adhesion 1510 g/cm and Izod impact strength 10.3 kg/cm2, compared with 702 g/cm and 2.5 kg/cm2, resp., for plates prepd. similarly from a compn. without I (only 15% of which was recovered in the pelletization step).

Rapidly curing epoxide compositions

Rapidly curing epoxide compositions. Dufek, Jan; Lidarik, Miloslav; Ditrych, Zdenek; Volny, Alois (Czech. ). Czech. CS 162329 15 Feb 1976,4 pp. (Unavailable). (Czechoslovakia). CODEN: CZXXA9. CLASS: IC: C09J003-16. APPLICATION: CS 73-5684 13 Aug 1973. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Epoxy sealing and adhesive compns. curing in 5-30 min at .In this article, certain chemicals are used. Some of their cas registry numbers are 24937-05-1 and 21544-03-6 ltoreq.170.degree. are prepd. which contain polyester, SiO2, HF-H3BO3 catalysts dispersed in polyols, and pigments and (or) heat-conductive fibers. Thus, bisphenol A-epichlorohydrin copolymer [25068-38-6] 700, poly(ethylene adipate) [24937-05-1] 300, SiO2 30, powd. Al 50, and HF-H3BO3-PhNH2 [62-53-3] (50% in triethylene glycol) 30 parts gave a compn. with 4-5 hr pot life at 20.degree. and 10 min curing time at 100.degree., used for sealing motor vehicle lenses and mirrors. .
