Acrylic polymers having a molecular weight of at leastabout 500,000, and preferably of about 1,500,000, are blended at levels of from 1 to 25% with thermoplastic resins to provide polymer blends having improved melt rheology, thereby to facilitate blow molding, thermoforming, extrusion and similar processes.
丙烯酸聚合物的分子量至少约为 500,000,最好约为 1,500,000,与热塑性
树脂的混合比例为 1%至 25%,以提供具有更好熔体流变性的聚合物混合物,从而促进吹塑、热成型、挤压和类似工艺。
