  • COPOLYESTER AND FOAM MATERIAL
    Publication number: 20240336726
    Abstract: A copolyester is formed by reacting 100 parts by weight of a polyester elastomer and 0.01 to 0.29 parts by weight of a compound having multi-functional groups. The polyester elastomer is formed by reacting polyethylene terephthalate, diol, and poly(alkylene ether)glycol. The polyethylene terephthalate and the diol have a weight ratio of 1:0.6 to 1:3, and the polyethylene terephthalate and the poly(alkylene ether) glycol have a weight ratio of 1:0.05 to 1:3.

  • COPOLYESTER AND HOT MELT ADHESIVE
    Publication number: 20240239986
    Abstract: A copolyester is formed by copolymerizing a depolymerized polyester and succinic acid. The depolymerized polyester includes depolymerized polyethylene terephthalate (PET), and the depolymerized PET is formed by depolymerizing PET with ethylene glycol. The repeating unit of PET and the succinic acid have a molar ratio of 40:60 to 50:50. The repeating unit of PET and the ethylene glycol have a molar ratio of 100:100 to 100:500. The copolyester has a storage modulus of 1*104 Pa to 1*106 Pa at 80° C. The copolyester can be used in a hot melt adhesive.
