摘要： The present invention discloses a semi-aromatic polyester, a preparation method therefor and use thereof. The content of hydroxyl in a semi-aromatic polyester is controlled, and particularly, the content of hydroxyl linked to aliphatic dicarboxylic acid in the semi-aromatic polyester is controlled to 17-40 mmol/kg, the content of hydroxyl linked to aromatic dicarboxylic acid in the semi-aromatic polyester is controlled to 17-40 mmol/kg, and the total content of hydroxyl is controlled to 35-80 mmol/kg, such that the compatibility of the semi-aromatic polyester with materials, e.g., polylactic acid can be significantly improved, thereby obtaining a high-strength tear-resistant film material.

摘要： Disclosed in the present invention is a semiaromatic polyester, a preparation method and application thereof. Having a specific segment length and carboxyl group content, the semiaromatic polyester provides a balance of degradation rate and mechanical properties, compared with known semiaromatic polyesters. The 30-day weight retention of the semiaromatic polyester obtained in the present invention may be contained to from 45 to 70%.

摘要： A polycarbonate alloy material, comprising the following components in parts by weight: 40-70 parts of polycarbonate; 20-40 parts of polyethylene terephthalate; and 0.1-2 parts of a metal compound. The metal compound is selected from any one of a metal oxide, a metal base, or a metal salt, and the metal is selected from any one of copper, iron, magnesium, calcium, titanium, antimony, sodium, or potassium. A certain amount of polyethylene terephthalate and a specific metal compound are added to the polycarbonate, such that a prepared polycarbonate alloy material has excellent chemical resistance, also has high melt strength and low melt cooling rate, and is applicable to extrusion blow molding processing to prepare a thick-walled and large-scale packaging container product, such that novel options of materials and molding approaches are provided for the field of packaging, the use requirements of drug packaging containers can be particularly satisfied, and the application of a polycarbonate material is further broadened.
