Abstract

The invention discloses a polyester terphthalate-sebate resin and a preparation method thereof. The polyester terphthalate-sebate resin is formed by polymerization of dibasic acid and diol. By mole percent, the diol is formed by 45-55 mol% of terephthalic acid and 45-55 mol% of sebacic acid. The diol is 1,4-butanediol, thermal performance parameters of the polyester terphthalate-sebate resin meet the following relational expression: T crystal peak width at half height / (T melting point-T crystallization temperature)=0.05-0.26; when the polyester terphthalate-sebate resin is used to manufacture a film with a thickness of 25+ / -1 [mu]m, the static friction coefficient is 0.2-0.3, the light transmittance is 90% or above, the light transmittance and the static friction coefficient of the film are balanced, the film also has a low static friction coefficient while maintaining high light transmittance performance, processing can also be performed smoothly without an opening agent or a compatilizer, and the prepared polyester terphthalate-sebate resin has good transparency and processing performance.

Description

technical field [0001] The invention belongs to the field of polymer synthesis, and in particular relates to a polyterephthalate-co-sebacate resin and a preparation method thereof. Background technique [0002] Polyterephthalate-co-sebacate resin is a copolymer of butylene sebacate and butylene terephthalate, polyterephthalate-co-sebacate The ester resin contains flexible aliphatic chains and rigid aromatic chains, so it has high toughness and high temperature resistance. Due to the existence of ester bonds, it is also biodegradable. It is very active in the research and market application of biodegradable plastics. One of the best degradable materials. [0003] However, in actual use, it is found that the crystallization rate of polyterephthalate-co-sebacate resin not only affects the transparency of the film material, but also affects the processing of the film. If the crystallization rate is too slow, the freshly blown film tends to be self-adhesive when it is rolled on...
