at the end of 1984, the co carbon company introduced the production of hexene copolymerized lldpe, followed by exxon, mobil&other companies. dow chemical (dow chemical company) almost used octylene as comonomer in its low pressure solution process,&nova canada (nova chemical) also used octylene in most of the pressure solution process. the copolymerization of octyl lldpe resin has a little good strength, tearing resistance&processing property, but the properties of hexene copolymerization&octyl copolymers he little difference. hexene lldpe resin manufacturers including exxonmobil chemical (exxon mobil chemical company), eastman chemical (eastman chem co), equistar (star company)&chevron phillips (chevron phillips chemical company) etc.. in addition, dow chemical (dow chemical company), basell (basel company),

pps的介电常数很小，介电损耗相当低，表面电阻率和体积电阻率对、温度、湿度的变化不，是优良的电绝缘材料，它的耐电弧时间也较长，pps的化学性相当，除了受强氧化酸，如浓酸、浓和王水的侵蚀外，它不受绝大多数酸碱盐的侵蚀，具有接近于ptfe的化学性。在低于175度时不溶于任何已知的，pps与一般时不会出现塑件开裂现象。pps由于分子链是由环和原子交替排列组成，本身具有阻燃作用，无须加入阻燃剂就可以达到ul-94-vo级水平。它的氧可达44%-53%，与pvc相近，是一种自熄性塑料，pps对紫外线、射线等也很，在照射时不会表面发粘或分解的现象。pps的主要不足是韧性较差，冲击强度较低，熔体粘度不够等。
