ABSTRACT:
The present invention provides a material for light-heat energy accumulation and conversion comprising a composition of a high-molecular compound having norbonadien derivative group as side chain with a catalytic matter converting a quadrycylan derivative group of high-molecular side chain into the norbonadien derivative group.
The invention also provides a material for light-heat energy accumulation and conversion, characterized by putting to an esterification reaction high-molecular compounds having an epoxy group as side chain with norbonadien carbonic acid or its derivative.
