随着聚合物工业的不断发展,同时合成工艺的不断开发和改进,目前有越来越多的高性能牌号的物料出现在市场中,比如,在聚烯烃包装领域,80年代问世的茂金属催化聚烯烃,具备很好的物理性能,但是加工性能不是很理想,在实际生产中很难单独使用茂金属的原料来加工。由于其熔体黏度过高, With the continuous development of the polymer industry and continuous development and improvement of synthetic processes, more and more high performance grades are currently on the market. For example, in the field of polyolefin packaging, the metallocene catalysis Polyolefins, with good physical properties, but the processing performance is not very satisfactory, in the actual production is difficult to separate the use of metallocene raw materials to processing. Due to its melt viscosity is too high,
