| 摘要 |
The present invention addresses the problem of providing a composition for soft materials, wherein the composition enables the production of a soft material that has excellent transparency, an excellent stress relaxation property and excellent strength and does not undergo the extreme decrease in an elongation degree even under high-temperature conditions. The present invention also addresses the problem of providing a soft material produced using the composition for soft materials. The present invention is a composition for soft materials, which comprises a polyrotaxane and a radically polymerizable monomer, wherein the polyrotaxane is composed of cyclic molecules, a linear molecule that penetrates through opening parts of the cyclic molecules in a skewered state and capping groups that respectively cap both ends of the linear molecule, and wherein the polyrotaxane has at least one cyclic molecule having a radically polymerizable group and the number of the radically polymerizable groups in the polyrotaxane is at least two. |
