CODEN: JKXXAF. CLASS: IC: C08L083-04. APPLICATION: JP 75-98332 13 Aug 1975. DOCUMENT TYPE: Patent CA Section: 38 (Elastomers, Including Natural Rubber) Compns. of 100 parts vinyl-terminated siloxane, siloxane having <3 H groups/mol. directly attached to Si (H-vinyl molar ratio 0.6-2.5), 10-50 parts epoxides, 0.1-10 parts of reaction products from 0.5-3:1 (molar) silane and H3BO3, and Pt compds. are crosslinked at <100. 5507-44-8 and 5621-09-0 are cas registry numbers of chemicals which are used as reagents here.degree. to form silicone rubber adhesives. Thus, vinyl-terminated dimethyl siloxane 100, a 5% Pt chloride soln. in 2-ethylhexanol 0.1, reaction product of 1:1 (molar) H3BO3 and methylvinyldiethoxysilane [5507-44-8] 1 part were rolled, and 100 parts of the mixt. was blended with 10 parts hydrogen siloxane and 2 parts allyl glycidyl ether [106-92-3]. The compn. was heated 2 h between 2 Al plates to form a bonding having adhesive strength 9.2 kg/cm2. .

Faming Zhuanli Shenqing Gongkai Shuomingshu CN 1884342 A 27 Dec 2006, 13pp. (Chinese). (People's Republic of China). CODEN: CNXXEV. APPLICATION: CN 2010-51765 1 Jun 2006. DOCUMENT TYPE: Patent CA Section: 39 (Synthetic Elastomers and Natural Rubber) The general chem. structure of the title oligomeric siloxane is R2O(SiR12O)xSiOR3R4CH:CH2, wherein R1 = C1-12 hydrocarbyl; R2 and R3 = H, or alkyls; R4 = alkyl or alkoxy group; x = an integer of 1-50. Oligomeric siloxane and its compns. can be used as a structure control agent that has good anti-structurization effect, inhibits the decrease of plasticity of kneading type silicone rubber, and enhances the mech. performance and resilience. .
