Abstract

Official abstract text for this publication.

The present invention relates to a polyrotaxane-containing composition including: a polyrotaxane that has a cyclic molecule, a linear molecule threading through a cavity of the cyclic molecule in a skewered manner, and capping groups capping both ends of the linear molecule; and an alkyl (meth) acrylate that has a C4-C18 alkyl group, the polyrotaxane having at least one cyclic molecule that has a C4-C18 alkyl group.

First claim

Opening claim text (preview).

The invention claimed is: 1. A polyrotaxane-containing composition comprising: a polyrotaxane that has a cyclic molecule, a linear molecule threading through a cavity of the cyclic molecule in a skewered manner, and capping groups capping both ends of the linear molecule; and an alkyl (meth)acrylate that has a C4-C18 alkyl group, wherein the cyclic molecule is a cyclodextrin, the polyrotaxane has at least one cyclic molecule that has a C4-C18 alkyl group, a radical polymerizable group, and a solubility-imparting group, the solubility-imparting group is a polyester chain, and the C4-C18 alkyl group of the polyrotaxane is introduced to a terminal reaction point of the polyester chain by reacting a hydroxy group of the polyester chain with an alkyl isocyanate, wherein the alkyl isocyanate has an isocyanate group and the C4-C18 alkyl group, and the isocyanate group is reactive with the hydroxy group. 2. The polyrotaxane-containing composition according to claim 1 , wherein the amount of the alkyl (meth)acrylate that has the C4-C18 alkyl group is 50% by mass or more. 3. The polyrotaxane-containing composition according to claim 1 , wherein the alkyl isocyanate consists of the isocyanate group and the C4-C18 alkyl group.
