相容剂的出现主要是为高分子材料合金技术服务的。所谓高分子合金，即由两种或两种以上具有不同性质的高分子材料经共混并采用相应的相容化技术而得到的多相多组分体系，而这样的高分子合金、共混、改性的重要关键材料就是相容剂。相容剂对合金技术的微观相态结构起到很好的调整和控制作用，从而使共混材料实现高性能化和功能化的效果。相容剂广泛应用于PP/PE、PP/PA、PA/PS、PA/ABS、ABS/PC、PBT/PA、PET/PA、PP/POE、PE/EPDM、TPE/PU等合金。
The appearance of compatibilizer mainly serves for polymer alloy technology. The so-called polymer alloy is a multi-phase and multi-component system obtained by blending two or more kinds of polymer materials with different properties and adopting corresponding compatibility technology. The key material of such polymer alloy, blending and modification is compatibilizer. The compatibilizer can adjust and control the microstructure of the alloy technology, so that the blend can achieve high performance and functional effect. Compatibilizers are widely used in PP / PE, PP / PA, PA / PS, PA / ABS, ABS / PC, PBT / PA, PET / PA, PP / POE, PE / EPDM, TPE / PU and other alloys.
二、相容剂应用在回收废旧塑料
2、 Application of compatibilizer in recycling waste plastics
利用相容剂回收废旧塑料，使之成为新的塑料合金或新的改性塑料，是“废物综合利用”比较好的可行办法，并可解决“白色污染”问题，具有很大的社会效益和企业经济效益。在国外已有很多先例，如荷兰国家矿业公司生产的BENNET相容剂，就是用于回收废旧塑料再生的专用相容剂，可以把两种或多种不同品种、不同性质的旧塑料，如聚烯烃塑料与工程塑料的边角料的共混再生
Using compatibilizer to recycle waste plastics and make them into new plastic alloy or new modified plastics is a better and feasible "comprehensive utilization of waste" and can solve the problem of "white pollution", which has great social and economic benefits for enterprises. There are many precedents in foreign countries, such as Bennet compatibilizer produced by Dutch national mining company, which is a special compatibilizer used for recycling waste plastics. It can blend two or more kinds of old plastics with different properties, such as polyolefin plastics and leftover materials of engineering plastics
