2016年考研国家线预测sheltered摘要：Extruded foam compris (P) a thermoplastic polymer comprising (P1) at least one styrene copolymer which compris copolymerized maleic anhydride units, (P2) at least one styrene-acrylonitrile copolymer, (P3) at least one thermoplastic polymer styrene polymers which are different from the components (P1) and (P2), polyacrylates, polycarbonates and polyesters, (F1) brominated trialkyl phosphate compounds (I) as a flame retardant, (F2) dicumyl compound or hydroxylamines or their anhydrides or mixtures as flame retardant synergist, and (Z) further additives. Extruded foam compris (P) a thermoplastic polymer comprising (P1) 50-100 pts. wt. at least one styrene copolymer which compris copolymerized maleic anhydride units, and exhibits a styrene content of 65-90 wt.%, bad on the component (P1), (P2) 0-50 pts. wt. at least one styrene-acrylonitrile copolymer exhibiting a styrene content of 65-90 wt.%, bad on the component (P2), (P3) 0-15 pts. wt. at least one thermoplastic polymer comprising styrene polymers which are different from the components (P1) and (P2), polyacrylates, polycarbonates, polyesters, polyamides, polyether sulfones, polyether ketones or polyether sulfides, (F1) 1-10 pts. wt., preferably 3-7 pts. wt. brominated trialkyl
2020语文高考phosphate compounds of formula ((O)P(OR) 3) (I) as a flame retardant, bad on the component (P), (F2) 0.01-3 pts. wt. dicumyl compound or hydroxylamines or their anhydrides or mixtures as flame retardant synergist, bad on the component (P), and (Z) 0-10 pts. wt. further additives, bad on the component (P). The total weight of the components (P1), (P2) and (P3) of the thermoplastic polymer is 100 pts. wt.. R : 1-6C alkyl (in which 1-3 H are substituted by Br). An independent claim is also included for producing the extruded foam, comprising (a) producing a polymer melt from the component (P), (b) introducing 1-12 pts. wt. a propellant component, bad on 100 pts. wt. the component (P), which compris carbon dioxide, into the polymer melt to form a foamable melt, and (c) extruding the foamable melt in a region of lower pressure under foaming to obtain the extruded foam.
