HEAT STORAGE MATERIAL COMPOSITION

摘要

A heat storage material composition that is excellent in shape retention and bleed resistance obtained by heat-treating Component (A) being a polyhydric alcohol not having constitutional units derived from any vinyl monomers, the following Polymer (B-1) and the following Polymer (B-2) together.
Polymer (B-1): A polymer composed mainly of constitutional units derived from acrylic acid or a salt thereof, a polymer composed mainly of constitutional units derived from methacrylic acid or a salt thereof, or a mixture thereof, excluding a polymer having two or more hydroxy groups in one polymer chain.
Polymer (B-2): A polymer composed mainly of constitutional units derived from a vinyl monomer, and having two or more hydroxy groups in one polymer chain.
