    • The present invention relates to use of a novel, single-component additive for addition to thermoplastics, in particular polyvinyl chloride (PVC). The resultant reduced friction delays melting of the thermoplastic during extrusion and therefore improves fluidity and lowers the process pressure required. The reduced friction moreover facilitates processing in shaping machinery by reducing adhesion to metal. In order to provide these technical improvements, the present invention provides a novel poly(meth)acrylate-based additive for thermoplastics, in particular for PVC. This features a poly(meth)acrylate backbone and long alkyl solid chains.
    • 本发明涉及新型单组分添加剂在热塑性塑料中的应用,特别是聚氯乙烯(PVC)。 所得到的减少的摩擦延迟了挤出期间热塑性塑料的熔化,因此提高了流动性并降低了所需的工艺压力。 减少的摩擦还有助于通过减少与金属的附着力在成形机械中进行加工。 为了提供这些技术改进,本发明提供了一种用于热塑性塑料的新型聚(甲基)丙烯酸酯类添加剂,特别是用于PVC。 其特征在于聚(甲基)丙烯酸酯主链和长烷基固链。
