The chain divergence medicine and the polyamide composition which includes that

摘要

This invention (a) at least 5 - 75 mass of the copolymer of the unsaturated di-carboxylic acid or that derivative and vinyl aromatic monomer of 1 %; (B) 5 - 75 mass of copolymer of acrylonitrile and vinyl aromatic monomer %; (0 - 80 mass of c) inactive processing aid %; And (d) 0 - 10 mass of the usual additive % it includes, here, (a) and (b) is miscibility, (a)/(b) ratio is, 1/3 - 3/1 at the same time regards the chain divergence medicine which (a) + (b) + (c) + (d) features that total is 100%, includes the anhydride basis. For example advantage of this chain divergence medicine in producing the polyamide composition which possesses non Newton melted flow behavior includes satisfactory reproducibility and the formation of the gel particle which decreases very. In addition as for this invention, it regards also the manufacturing method of the chain divergence medicine and the manufacturing method of the polyamide composition which possesses non Newton melted flow behavior, and the method of using that kind of polyamide composition for the production of the formation item.
