hdpe的品级一般具有的分子量范围是40000～300000，重均分子量大致与熔融范围相对应，即从100～0.029g/10min230℃，2.16kg。通常地，更高的mw的熔融mi增强了熔体强度、韧性和escr，但是更高mw使加工更难或且需要更高的压力或温度。分子量分布mwd：pe的wd根据使用的催化剂和加工而有从窄到宽的不同。常用的mwd测量是不匀度hi，它等于重均分子量mw除以数均分子量mn。所有hdpe品级的这个范围是4-30。窄mwd提供了在模塑中的低翘曲性和高冲击性。中到宽mwd提供了对多数挤塑的可加工性。宽mwd也可改进熔体强度和抗蠕变性。

the cauldron is the main equipment, which is made of stainless steel/enamel lined with steel kettle, equipped with agitator&heat transfer jacket for controlling temperature,/internal cooling pipe, reflux condenser&so on. in order to reduce the production cost, the volume of the reactor has expanded from several cubic meters to a dozen cubic meters. the largest volume has reached 200 cubic meters. when the polymerizer is used many times, it needs to be descaled. pvc, made of polyvinyl alcohol&cellulose ether as suspended stabilizer, is generally loose, porous&large in surface area. it is easy to absorb plasticizer&plasticizing.
