Amino-terminated polypropylene and preparation method thereof

Abstract

The invention relates to amino-terminated polypropylene, wherein one end of a macromolecular chain carries with an amino group, the structure of the amino-terminated polypropylene accords with to general formula (I). The amino-terminated polypropylene is obtained by reacting a hydroxyl group of hydroxyl-terminated polypropylene with acyl-chlorinated diacid and further reacting the obtained polypropylene which carries an acid acyl chloride group at the terminal with diamine. The amino-terminated polypropylene has strong polarity and has wide application in the fields of polymer blend, composite materials and the like.

Description

Amino-terminated polypropylene and its preparation method technical field The invention relates to an amino-terminated polypropylene and a preparation method thereof. technical background Polyolefin is a material with a wide range of applications, but the molecular chain of polyolefin is completely composed of saturated hydrocarbons and lacks polar functional groups. The adhesion, printing and dyeing properties of polyolefin and the compatibility with other polymers or fillers are poor, which limits the application of polyolefin in many aspects. Therefore, it is of great practical significance to introduce polar functional groups into polyolefins to realize the functionalization of polyolefins. However, the chemical stability of polyolefin chains makes the functionalization of polyolefins more difficult, and the functionalization of polyolefin end groups is more difficult than the functionalization of polyolefin side chains. However, since the terminal functional group o...
