摘要
在聚丙烯中试装置上进行催化剂和助剂配方的筛选以及聚合工艺的优化等研究,开发了聚丙烯瓶盖专用树脂YPJ-706,并在工业装置上生产出弯曲模量大于1.4 GPa,常温冲击强度大于或等于8.0kJ/m^2的高性能产品,可满足瓶盖制品的加工要求。
Polypropylene （PP） speciality resin for bottle caps, YPJ-706, was developed through catalyst screening, polymerization process optimization and additives formula study in a PP pilot plant. Furthermore, a corresponding high-performance grade with flexural modulus over 1.4 GPa, impact strength at normal temperature equal to or higher than 8.0 kJ/m^2 was produced in a PP industrial plant to satisfy requirements for processing bottle caps.
