外文摘要：Poly(vinyl acetate-co-vinyl alcohol)s (P(VAc-co-VA)s) with different degree of hydrolysis (DH) were blended with polylactide (PLA) by melt mixing to prepare PLA/P(VAc-co-VA) blends with various weight ratios. PLA and PVAc were miscible. For blends of PLA and P(VAc-co-VA) with DH from 13.8 similar to 55.1%, PLA and P(VAc-co-VA) s were partly miscible. For PLA/P(VAc-co-VA(14)) blends with P(VAc-co-VA(14)) of 5-50wt.%, PLA/P(VAc-co-VA(33)) with P(VAc-co-VA(33)) of 5-50wt.%, and PLA/P(VAc-co-VA(55)) with P(VAc-co-VA(55)) of 5-20 wt.%, P(VAc-co-VA)s were dispersed in PLA uniformly. The size of dispersed phase changed with the content and DH of P(VAc-co-VA). When the content of P(VAc-co-VA(55)) in PLA/P(VAc-co-VA(55)) blends was above 30 wt.%, the dual continuous phase formed.
