The synthetic technique of new type high molecular ashless dispersant of polybutene (PBP) and dimaleic anhydride was described. 介绍了新型高分子聚异丁烯双马来酸酐无灰分散剂的合成工艺。
Polybutene and polyisobutylene are liquid oligomers widely used as plasticizers for high-molecular weight polymers, such as polyethylene, and as carriers and lubricants. They are not to be confused with the high molecular weight polymer polybutene-1.
