摘要： The present invention discloses a polyester, a preparation method therefor and use thereof. The polyester includes repeating units derived from the following components: a first component A, based on the total molar weight of the first component A, including: a1) 81-100 mol% of succinic acid, or an ester derivative thereof or an anhydride derivative thereof, and a2) 0-19 mol% of a dicarboxylic acid other than succinic acid, or an ester derivative thereof or an anhydride derivative thereof; a second component B: 1,4-butanediol; and a third component C: a dimer(1,4-butanediol); based on the total molar weight of the first component A, the molar content of the repeating unit -CH2CH2CH2CH2-O- in the third component C is 0.05-3.0 mol%. In the present invention, the molar content of the repeating unit -CH2CH2CH2CH2-O- in dimer(1,4-butanediol) is controlled to 0.05-3.0 mol%, and thus, the resin color of the polyester can be effectively improved.

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 are a polypropylene composite material capable of cracking at a low temperature, and a preparation method therefor and use thereof. The polypropylene composite material comprises the following components in parts by weight: 35-75 parts of special polypropylene A, 3-10 parts of special polypropylene B, 15-30 parts of a filler, 2-10 parts of a special toughening agent, 15-25 parts of a toughening agent, 0.1-0.3 part of a lubricant, 0.1-0.3 part of a photo stabilizer, and 0.2-0.6 part of an antioxidant, wherein the special toughening agent comprises ultrahigh molecular weight polyethylene and a metallocene ethylene-propylene copolymer. The polypropylene composite material that is capable of cracking at a low temperature and has good rigidity is prepared by using the special polypropylene A, the special polypropylene B, and the special toughening agent in combination with the normal filler and the normal toughening agent, and the polypropylene composite material has a wide application prospect (for example, in automotive interior parts such as a bare column capable of cracking at a low temperature).
