Patent ID: 8173758

Claim:
A polysiloxane represented by the formula (2): where in the formula (2): R independently represents alkyl having 1 to 45 carbon atoms whereby optional hydrogen may be replaced by fluorine and optional —CH 2 — may be replaced by —O—, —CH═CH—, or cycloalkylene; cycloalkyl having 4 to 8 carbon atoms; substituted or unsubstituted aryl whereby optional hydrogen on aryl may be replaced by halogen or alkyl having 1 to 10 carbon atoms in which optional hydrogen may be replaced by fluorine and optional —CH 2 — may be replaced by —O—, —CH═CH—, or phenylene; or substituted or unsubstituted arylalkyl whereby optional hydrogen on aryl may be replaced by halogen or alkyl having 1 to 10 carbon atoms in which optional hydrogen may be replaced by fluorine, and optional —CH 2 — may be replaced by —O—, —CH═CH—, or phenylene, and alkylene of the arylalkyl has 1 to 10 carbon atoms whereby optional hydrogen may be replaced by fluorine and optional —CH 2 — may be replaced by —O—, —CH═CH—, or phenylene; n represents an integer of 1 to 1,000; R 2 independently represents —Si(A) 3 whereby A independently represents hydrogen; alkyl having 1 to 10 carbon atoms whereby optional hydrogen may be replaced by hydroxyl, halogen, carboxyl, ester, 2,4-dioxo-3-oxacyclopentyl, acetoxy, amino group, isocyanate, oxiranyl, 3,4-epoxycyclohexyl, oxetanyl, cyano, vinyl, (meth)acryloyl, 4-vinylphenyl, alkyleneoxy, or mercapto, and optional —CH 2 — may be replaced by —O—, —CH═CH— or phenylene; or phenyl.
