Abstract
A temperature regulating article comprises a substrate and a polymeric phase change material bound to the substrate, wherein the polymeric phase change material is characterized by including a precisely branched polymer with substantially equally spaced repeating sidechains. In other embodiments the polymeric phase change material includes between 20 and 200 branches per 1000 carbon units, has a latent heat of at least 5 Joules per gram, and a transition temperature between 0° C. and 40° C.
