Abstract
The present invention aims to provide a polyrotaxane-containing composition having excellent transparency. 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.
Claims3
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.
