摘要： The present invention relates to a method for the manufacture of polypropylene having a target melt flow rate of from 10 to 200 g/10 min as determined in accordance with ISO 1133 (230° C., 2.16 kg) comprising the sequential steps of i) polymerizing propylene monomer, and optionally one or more alpha olefin co-monomers so as to form a polypropylene having an initial melt flow rate of from 0.5 to 20 g/10 min (ISO 1133, 230° C., 2.16 kg), ii) visbreaking said polypropylene to obtain polypropylene having said target melt flow rate and wherein the ratio of target to initial melt flow rate is more than 1 iii) maintaining the polypropylene obtained from step ii) at an elevated temperature for a time sufficient to reduce the FOG value of the polypropylene as determined in accordance with VDA 278. The method allows the time for FOG reduction to be reduced as compared to polypropylenes that have the same target melt flow rate, yet which have obtained said melt flow rate without the visbreaking step.
摘要翻译：本发明涉及根据ISO 1133（230℃，2.16kg）测定的具有10至200g / 10min的目标熔体流动速率的聚丙烯的方法，包括以下顺序步骤：i）聚合丙烯单体和任选的一种或多种α-烯烃共聚单体，以形成初始熔体流动速率为0.5至20g / 10min（ISO 1133,230℃，2.16kg）的聚丙烯，ii）减粘裂化所述聚丙烯以获得具有所述目标熔体流动速率的聚丙烯，并且其中目标与初始熔体流动速率的比率大于1 iii iii）将在步骤ii）中获得的聚丙烯保持在升高的温度足以降低FOG值根据VDA 278确定的该聚丙烯。与具有相同目标熔体流动速率的聚丙烯相比，该方法允许减少FOG的时间，但是在没有减粘裂化的情况下获得了所述熔体流动速率步。
