PHOTOCROSSLINKABLE POLYROTAXANE, COMPOSITION COMPRISING THE PHOTOCROSSLINKABLE POLYROTAXANE, CROSSLINKED BODY DERIVED FROM THE COMPOSITION, AND METHOD FOR PRODUCING SAME

Document Type and Number:

Japanese Patent JP2014224270

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a photocrosslinkable polyrotaxane having a high scratch resistance, low hysteresis loss and the like; a composition comprising the photocrosslinkable polyrotaxane and the like; a crosslinked body obtained from the composition; and a method for producing the same.SOLUTION: In the photocrosslinkable polyrotaxane, a cyclic molecule of a polyrotaxane has a group represented by -M-Y (wherein M is represented by formula II mentioned below; X represents a straight-chain alkylene group having 1-8 carbon atoms, or the like; n is 1-10 on average; and Y represents a group having a photopolymerizable group), wherein the polyrotaxane is formed by arranging blocking groups at both ends of a pseudo-polyrotaxane to prevent the withdrawal of the cyclic molecule, and the pseudo-polyrotaxane is formed by piercing the opening of the cyclic molecule by a straight-chain molecule to form a clathrate therewith. A composition comprising the photocrosslinkable polyrotaxane and the like, a crosslinked body derived from the composition, and a method for producing the same is also provided.
