PHOTOCROSSLINKABLE POLYROTAXANE, COMPOSITION COMPRISING THE PHOTOCROSSLINKABLE POLYROTAXANE, CROSSLINKED BODY DERIVED FROM THE COMPOSITION, AND METHODS FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2011/105532
Kind Code:
A1
Abstract:
Disclosed are: a photocrosslinkable polyrotaxane having a high scratch resistance, low hysteresis loss and so on; a composition comprising the photocrosslinkable polyrotaxane and so on; a crosslinked body obtained from the composition; and methods for producing the same. Specifically disclosed are: a photocrosslinkable polyrotaxane comprising a cyclic molecule of polyrotaxane, wherein pseudo-polyrotaxane is formed by piercing the opening of a cyclic molecule by a straight-chain molecule to form a clathrate therewith and blocking groups are positioned at both ends of the pseudo-polyrotaxane to prevent the withdrawal of the cyclic molecule, said cyclic molecule of polyrotaxane having a group represented by -M-Y [wherein M is represented by formula (II); X represents a straight-chain alkylene group having 1-8 carbon atoms, etc.; n is 1-10 on average; and Y represents a group having a photopolymerizable group]; a composition comprising the photocrosslinkable polyrotaxane and so on; a crosslinked body derived from the composition; and methods for producing the same.
