Abstract
A high-temperature endurable phase-change polymer has a polyether main chain and two fatty acyl terminals. The polyether main chain is polyethylene glycol or polytetramethylene glycol. The two fatty acyl terminals are preferably stearoyl group, palmitoyl group, or lauroyl group.
Claims16
A high temperature endurable phase change polymer comprising a polyether fatty acid ester undergoing physical phase changes from solid phase to liquid phase or liquid phase to solid phase in an approximate temperature range of about 0-80° C. and having a maximum thermo-gravimetric-loss temperature of at least about 350° C.
A method of making a high temperature endurable phase change polymer comprising esterifying a polyether diol with a fatty acid or a fatty acyl halide selected from the group consisting of fatty acyl chlorides, fatty acyl bromides, and fatty acyl iodides.
