    摘要: Provided is a method for producing an anionic polymer in an industrially advantageous manner, whereby at the time of anionically polymerizing monomers using a solvent whose boiling point at atmospheric pressure is higher than the polymerization temperature, temperature control can be achieved by quickly removing the heat of the polymerization reaction using a simple device. The method for producing an anionic polymer includes anionically polymerizing a conjugated diene, an aromatic vinyl compound, or a mixture thereof under a condition where the amount of an inert gas present with respect to 1 kg of a solvent whose boiling point at atmospheric pressure is higher than the polymerization temperature is 20 mmol or less.

    摘要: 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.
