作者（2019）在《Miscibility and Crystallization Behavior of Novel Branched Poly(ethylene succinate)/Poly(vinyl phenol) Blends》一文中研究指出：The blends of novel branched poly(ethylene succinate)(b-PES) and poly(vinyl phenol)(PVPh) were prepared via a solution and casting method.The miscibility,melting behavior,spherulitic morphology and growth,and crystal structure of b-PES/PVPh blends were investigated in detail.PVPh was miscible with b-PES over the whole compositions as evidenced by the single composition dependent glass transition temperature.Double melting behavior occurred in neat b-PES and b-PES/PVPh 85/15 blend after isothermal melt crystallization,which may be explained by the melting,recrystallization,and remelting mechanism.In addition,the depression of equilibrium melting point of an 85/15 blend was also found,confirming again the miscibility between the two components.The addition of PVPh caused the decrease of nucleation density and crystal growth rates of b-PES spherulites in the blend.The crystal structure of bPES was unchanged before and after blending;moreover,the crystallinity of b-PES decreased slightly in the blend.
