摘要: Miscibility and crystallization of biodegradable poly (3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHHx)/poly(vinyl phenol) (PVPh) blends were investigated in this work. PHBHHx is miscible with PVPh over the whole composition range as evidenced by single dependent glass transition temperature depression equilibrium melting point blends. The overall rates decrease increasing for both neat its PVPh; moreover, are slower PHBHHx/PVPh than at same temperature. Blending may change mechanism compared that PHBHHx. Both exhibit a regime II to III transition. crystal structure not modified blends; however, values layer thickness, amorphous long period all become larger content POLYM. ENG.
