ABSTRACT:
A phase-reversible composition is disclosed, which is liquid at a low temperature and solid at a high temperature, the phase being reversible. The composition includes a conjugated diene-maleic acid derivative copolymer having a sulfur containing organic terminal radical of from 4 to 30 carbon atoms, which radical contributes to increased surface-activity and compatibility of the final composition.
