摘要： The properties of a thermoformed polymeric article are modified by incorporation of an additive in a thermoplastic/thermoplastic elastic host matrix. The additive comprises a polydispersed hyperbranched polymer (HBP) or a branched monodispersed dendritic polymer (DP). The HBP or DP is linked to a plurality of oligomer chains. The additive migrates to the surface of the article during the thermoforming process.
