摘　　要：Comb-like acrylic acid poly（ethylene glycol） methyl ether ester （MPEGA）-co-acrylamide （AM） copolymer [P（MPEGA-co-AM）] as novel phase change materials （PCMs） was successfully synthesized via free-radical water solution polymerization. The structures of P（MPEGA-co-AM） was characterized by Fourier Transform Infrared （FT-lR）. The experimental results showed that P（MPEGA-co-AM） copolymer possessed high molecular weight （Mo =66 kg/mol）, narrow molecular weight distribution （PDI≈1.14）. The phase transition temperature of copolymer decreases to 31℃, which is very much appreciated and urgently needed for smart PCM related to human body. Moreover, P（MPEGA-co-AM） had good thermal stability even at 380℃.Comb-like acrylic acid poly（ethylene glycol） methyl ether ester （MPEGA）-co-acrylamide （AM） copolymer [P（MPEGA-co-AM）] as novel phase change materials （PCMs） was successfully synthesized via free-radical water solution polymerization.
