Abstract

The invention discloses a blended resin composition. Based on the total weight of 100 percent, the resin composition is formed mainly by blending 60 to 99 weight parts of aromatic polyesters and 40 to 1 weight part of aliphatic polyesters. In addition, the resin composition also contains a compatibilizer in an amount of 0.5 to 10 percent based on the total weight of the composition, wherein the compatibilizer is obtained by polymerizing active epoxy group-containing olefine acid esters. In the blended resin composition, the aliphatic polyesters serving as a disperse phase are dispersed in the aromatic polyesters serving as a continuous phase, and have the mean grain size of less than 600 nm. The resin composition provided by the invention can keep the heat resistance of conventional polyesters and reduce the using amounts of petrochemical raw materials, is applied to apparel fibers, optical thin films, various moldings, outer plate parts of buffer bars, doors and the like of automobiles, structural parts of the automobiles, and the like, and compared with the conventional polyesters, produces lower environmental load and has high utilization value.

Description

technical field [0001] The invention belongs to the field of macromolecular materials, and specifically relates to a polyester alloy obtained by compounding aromatic polyesters and aliphatic polyesters in the presence of a compatibilizer through physical compatibility and / or chemical combination. Background technique [0002] Aromatic polyesters such as polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), polybutylene terephthalate (PBT), etc., have good chemical stability , processability, heat resistance, and dimensional stability, and are widely used in the fields of fibers, films, and molding materials. [0003] The main raw materials of aromatic polyesters, such as terephthalic acid, ethylene glycol, 1,3-propanediol, 1,4-butanediol, etc., are mainly synthesized from petroleum-derived raw materials through chemical reactions. As aromatic polyester is a kind of petrochemical material, it has extremely high hydrolytic stability under normal circumstance...
