聚烯烃塑料改性的研究进展

Advance in Modification of Polyolefin Plastics

聚乙烯、聚丙烯以优良的力学性能、热性能、加工性能等成为最主要的聚烯烃塑料品种,大量用于生产薄膜、管材和板材。通过改性可获得高刚性、高强度、高耐热、低成本的聚烯烃塑料。综述了近年来聚乙烯和聚丙烯在接枝、交联、填充、共混等方面的改性进展,并指出了研究方向和发展趋势。

Polyethylene and polypropylene with many desirable mechanical and thermal properties are two dominant materials among synthetic resins. They were applied widely in manufacturing films, pipes and panels. The polyolefin composite plastics possess high rigidity, high strength, high heat- resistance and low cost by modification. Advance in modification of polyethylene and polypropylene, namely grafting, crosslinking, filling and blending, was reviewed and the development trend was discussed.
