Abstract
One of the purposes of the present invention is to provide a polysiloxane which has polymerizable groups at the both terminals, is well compatible with another hydrophilic monomer, and provides a (co)polymer having improved durability of mechanical strengths. The present invention provides a compound represented by the formula (1) having a group represented by the formula (3) as a hydrophilic side chain, which is characterized in that the hydrophilic side chain has an alkyl group having three hydroxyl groups and no ether bond. Further, the present invention provides a method for preparing the silicone.
