Acrylobutadiene styrene

Effect of different components in multicomponent blends based on polyamide 6 (PA 6) and styrenic polymers. Addition of a reactive compatibilizer maleic anhydride grafted styrene acrylonitrile (SANMA) changed the matrix-dispersed particle structure of PA6/styrene acrylonitrile (SAN) to a cocontinuous one. Replacement of part of SAN by polybutadiene particles led to a coarse cocontinuous structure (PA6/acrylobutadiene styrene [ABS]), which was refined after compatibUizer addition. SEM of cut surfaces etched in different solvents. (A) PA6/SAN = 50/50 wt%, SAN etched in tetrahydrofurane (B) PA6/ABS = 50/50 wt%, PA6 etched in formic add (C) PA6/ABS = 50/50 wt%, SAN etched in tetrahydrofurane (D) PA6/SAN+SANMA, PA6 etched in formic add (E) PA6/ABS+ SANMA, PA6 etched in formic add and (F) PA6/ABS = 50/50 wt%, PA6 etched in formic add.

Tables 10 and 11 show pultruded materials with glass fiber and carbon fiber respectively. For both tables the following abbreviations have been used PP-polypropylene, PMMA-poly (methyl methacrylate), PU-polyurediane, NY6-nylon 6, PPS-polyphenylene sulfide, UP-unsaturated polyester, PH-phenolic resin and ABS-acrylobutadiene styrene.
