Reinforced propylene polymer compositions. (Ube Industries, Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58145750 A2 30 Aug 1983 Showa, 6 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08L051-00; C08K007-14. APPLICATION: JP 82-26741 23 Feb 1982. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Compns. prepd. from peroxides, stabilizers, unsatd. silanes, ￡ ethylene-propylene block copolymer (I) [9010-79-1] (melt index ￡1.0 g/10 min), glass fibers, and optionally aminosilanes have good rigidity and impact resistance. 614-45-9 and 9010-79-1 which are cas registry numbers of chemicals are mentioned. Thus, 3-(trimethoxysilyl)propyl methacrylate [2530-85-0] 0.3, tert-BuOOBz [614-45-9] 0.25, 6:94 I (melt index 0.35 g/10 min) 100, Irganox 1010 0.1, and BHT 0.1 part were extruded at 220°, mixed (80 parts) with 20 parts glass fibers, and molded. .

Primer compositions

Primer compositions. (Toray Silicone Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58162660 A2 27 Sep 1983 Showa, 8 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08L083-04; C09J003-16. APPLICATION: JP 82-44217 19 Mar 1982. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Silicone primers providing heat-resistant bonding between metals and silicone rubbers comprise an organopolysiloxane with R1aSiO(4-a-b)/2(OR2)b units (R1 = hydrocarbon group of 35 mol% Ph; R2 = H, alkyl; a = 0.90-1.80; b = a numerical value for Si-bonded OH or alkoxy groups to be >0. 17927-72-9 and 12597-68-1 which are cas registry numbers are also used here.01%) 100, an alkoxysilane R3nSi(OR4)4-n or its hydrolyzate (R3 = unsatd. aliph. hydrocarbon group; R4 = alkyl; n = 1,2) 20-400, an org. Ti compd. 2-100, and an amino silane or its hydrolyzate 0.5-100 parts in org. solvents. Thus, a primer from Me Ph polysiloxane (MeSiO3/2 20, PhSiO3/2 40, Me2SiO 20, Ph2SiO 20 mol%; HO group content 3%) 100, [3-(methacryloyloxy)propyl]trimethoxysilane [2530-85-0] 100, diisopropoxytitanium bis(acetylacetonate) [17927-72-9] 10, toluene 430, and [3-(2-aminoethylamino)propyl]trimethoxysilane [1760-24-3] 10 parts was coated on mild steel, Al, stainless steel, and Ni plates and dried at room temp. for 30 min. The coated plates were pressed with 4 mm silicone rubber stock sheets (SH52U) contg. 0.5% 2,5-dimethyl-2,5-bis(tert-butylperoxy)hexane at 170°/30 kg/cm2 for 10 min to give specimens showing no peeling for 20 days in silicone oil at 200° or in an air oven at 230°. .
