(Germany). CODEN: GWXXBX. CLASS: IC: C07F007-18. APPLICATION: DE 76-2655877 9 Dec 1976. DOCUMENT TYPE: Patent CA Section: 38 (Elastomers, Including Natural Rubber) Section cross-reference(s): 29 Aliph. double bond-contg. organosilanes, prepd. by treating silanes with allyloxyalkanes in the presence of metallic catalysts, improve the adhesion of polymers to fillers. Thus, treatment of tetrakis(allyloxy)ethane [16646-44-9] with triethoxysilane [998-30-1] in the presence of H2PtCl6.6H2O gave (CH2:CHCH2O)2CH(OCH2CH:CH2)[O(CH2)3(SiOEt)3] (I) [67380-44-3] which when added to an ethylene-propylene-butadiene copolymer [25189-22-4] rubber stock contg. a kaolin filler provided vulcanizates having 100% modulus 2.20 N/mm2, Shore A hardness 50, tensile strength 6.43 N/mm2, elongation at break 547%, tear strength 5.0 N/mm, and crosslink d. 624 N m, vs. 2.52, 53, 6.37, 278, 4.9, and 702 for a vulcanizate contg.
