聚合物反应加工的现状与发展动向 总被引:1,自引:0,他引:1
几十年来,塑料工业一直发展很快。现在,其体积产量几乎可与钢铁产量相匹敌。单台设备挤出造粒的处理量最高已超过35吨/时。特别是以高附加值为目标的高分子合金和共混材料(PAB)年增长率超过13%,为整个塑料工业增长率的四倍,已成了发展最快的领域之一。以此为背景,一方面对传统的生产工艺中的脱低分子物、干燥、造粒工序 相似文献

In this work, the sequence distribution of copolymers generated in anionic copolymeriza-tion with a constant comonomer ratio has been theoretically investigated by means of non-steady state kinetic technique. The microstructural parameters of the copolymer, such as se-quence distribution functions, the average length of sequence and mole fractions of dyads andtriads, are derived by rigorously solving the kinetic differential equations. Furthermore, theseparameters are connected with reaction time and initial conditions and therefore become pre-dictable. 相似文献
