Abstract
Composizioni termoplastiche da stampaggio, aventi ottime caratteristiche di distacco dallo stampo e migliorate proprietà fisico-meccaniche ad elevate temperature di stampaggio, comprendenti:A) un copolimero vinil aromatico antiurto consistente di un nitrile etilenicamente insaturo, un monomero vinilaromatico e una gomma;B) un tecnopolimero;C) una quantità efficace di un agente distaccante costituito da una miscela sinergica di un estere di un acido C16-C18 con glicerolo e un estere di un acido saturo alifatico C18-C20 con un alcol alifatico C4-C6; e D) un bis (alchil-fenil) pentaeritritolo difosfito.Le composizioni possono inoltre contenere in aggiunta un polimero graffato costituito da un'anima elestomerica avente una Tg inferiore a 10°C contenente graffate catene di monomeri vinilici.
