    摘要: A siloxane gum is prepared by adding a silane or siloxane having two hydrolyzable groups in a molecule to a silanol-terminated organopolysiloxane in such an amount to give a molar ratio of silanol group/hydrolyzable group of from 0.5 to 3 and effecting condensation polymerization. The resulting organopoly-siloxane has a degree of polymerization of higher than 1,000 and a minimized content of low-molecular weight cyclic siloxanes of less than 5,000 ppm.

    摘要: A method of producing a silicone rubber composition, comprising heating a mixture of an organopolysiloxane having a silanol group at both the ends of the molecular chain, a end blocking agent, such as a triorganosilanol, a silane or a siloxane having two dialkylaminosilyl groups in the molecule, and a reinforcing filler thereby carrying out chain lengthening and end blocking of said organopolysiloxane. According to this method, a silicone rubber composition whose low-molecular siloxane content is held down remarkably can be produced without consuming a large amount of energy for the mixing.

    摘要: Organopolysiloxanes having a silanol group at both terminal ends of molecular chain thereof are brought into condensation reaction with each other in the presence of a silane or siloxane having at least two dialkylaminosilyl groups per molecule as a condensation catalyst and a triorganosilanol or other endblocking agent, to lengthen the chain of the organopolysiloxane under reaction, whereby a triorganosilyl-endblocked organopolysiloxane with a high polymerization degree is obtained. The process yields a triorganosilyl-endblocked high-polymerization-degree organopolysiloxane while effectively suppressing or preventing the formation of low-molecular-weight siloxanes.
