[0483] Any crosslinked organopolysiloxane can be used without limitation on the physical mode or production method (such as dilution), properties, etc., provided it is a crosslinked organopolysiloxane such as those described above. Particularly preferred examples thereof include α,ω-diene crosslinked silicone elastomers described in U.S. Patent No. 5,654,362 (commercially available products include DC 9040 silicone elastomer blend, DC 9041 Silicone Elastomer Blend, DC 9045 Silicone Elastomer Blend, DC9046 Silicone Elastomer Blend, EL-9140 DM Silicone Elastomer Blend, 9546 Silicone Elastomer Blend, 9027 Organic Silicone Elastomer Blend, FB-9586 Silicone Elastomer Blend, and EL-8040 ID Silicone Organic Blend). In addition, examples of partially crosslinked organopolysiloxane polymers include: (Dimethicone / Vinyl Dimethicone) Crosspolymer, (PEG-8 to 30 / C6 to C30 Alkyl Dimethicone) Crosspolymer, (Vinyl Dimethicone / C6 to C30 Alkyl Dimethicone) Crosspolymer cross-linked polymer, (p...

Abstract

A liquid organopolysiloxane having fluidity at at least 100°C, a silicon-bonded glycerin derivative group, and a crosslinked structure comprising a carbon-silicon bond at the crosslinking portion.

Description

technical field [0001] The present invention relates to novel liquid organopolysiloxanes with a crosslinked structure and uses thereof. This application claims priority from Japanese Patent Application No. 2011-286976 filed on December 27, 2011, the contents of which are incorporated herein by reference. Background technique [0002] As a liquid organopolysiloxane having a hydrophilic group and a crosslinking portion, a product obtained by reacting a specific alkylene oxide derivative, a specific silicone derivative and a specific isocyanate compound has been reported as Excellent defoamer for industrial use (see Patent Document 1). However, this material uses highly hazardous isocyanate as a raw material. Therefore, there are obstacles to using this material from the standpoints of safety, refining cost, and the like. [0003] In addition, as a liquid organopolysiloxane having a hydrophilic group and a crosslinking portion, there is disclosed wherein at least two organop...
