Polyrotaxane, water-based polyrotaxane dispersion composition, and cross-linked product of the polyrotaxane and the polymer, as well as methods for their preparation

摘要

The present invention provides a polyrotaxane capable of using an aqueous solvent in the working process, even while having a hydrophobic, water-based composition having the polyrotaxane, a crosslinked body and comprising a said polyrotaxane. A polyrotaxane formed by arranging blocking groups cyclic molecule to prevent the dissociation across step of blocking the opening of the cyclic molecule formed by the inclusion skewered shape by the linear molecule, the present invention, the cyclic molecule There group represented by the following formula I, a group represented by the following formula II, and a group represented by the following formula III, and to provide such a polyrotaxane. In addition, M is, for example, include a group of ring-opening polymerization of ε- derived from caprolactone, A is such as a hydroxyl group, B, etc. -COOH groups, C shows the A and / or B. -M-A formula I; -C Formula III and; -M-B-type II.
