## Abstract Poly(vinyl acetate) (PVAc) was added to the crystalline blends of poly(ethylene oxide) (PEO) and poly(Lโlactide) (PLLA) (40/60) of higher molecular weights, whereas diblock and triblock poly(ethylene glycol)โpoly(Lโlactide) copolymers were added to the same blend of moderate molecular w
Poly(vinyl acetate) (PVAc)/poly(ethylene oxide) (PEO) blends were prepared by casting from either benzene or chloroform. The solvent effects on the crystallization behavior and thermodynamic properties of the blends were studied by the differential scanning calorimeter (DSC). Two grades of PEO with
## Abstract Polystyreneโgrafted poly[ethyleneโ__co__โ(vinyl acetate)] (EVAโgโPS) has been synthesized from functionalized polystyrene containing acyl chloride end group (PSโCOCl) and partly (5%) hydrolyzed poly[ethyleneโ__co__โ(vinyl acetate)] (EVALVAโ5%). The graft efficiency is ca. 100% when lowโ
To obtain a correlation among structure-morphology-mobility-compatibility properties of poly(ethylene-co-vinyl acetate) (EVA)/poly(vinyl acetate) (PVAc) blends, we have used scanning electron microscopy and solid-state nuclear magnetic resonance in our investigations. The results are discussed in te
