POLYROTAXANE-CONTAINING COMPOSITION.

摘要

The objective of the present invention is to provide a polyrotaxane-containing composition having superior transparency. The polyrotaxane-containing composition contains an alkyl(meth)acrylate having an alkyl group having 4-18 carbon atoms, and a polyrotaxane comprising a cyclic molecule, a straight-chain molecule skewering through the opening of the cyclic molecule, and a blocking group that blocks the ends of the straight-chain molecule. The polyrotaxane has at least one cylic molecule having an alkyl group having 4-18 carbon atoms.
