1.Abstract: Unsaturated polyester with low shrinkage composied of anti-shrinking agent,thermoplastics,dispersion-stabilizer,a kind of graft copolymer made from styrene and saturated polyester,shaped like a comb for its molecular structure and UPR in certain structure and some factors effecting on low shrinkage were introduced in this paper.
2.In this paper,the performance of flocculation and purification of agent CGP-B have been studied in detail under various conditions, which is a kind of natural graft-copolymerised high polymer agent, as far as the flocculation of high density surfactant wastewater is concerned.
