Abstract
The studies of polymer blends for industrial applications is widespread owing to the possible diversity of such blends. In addition to binary blends in which both components are amorphous, blends that consist of a crystalline and an amorphous polymer have received particular attention. One such system studied in detail in the literature is that of blends of poly(ethylene oxide) (PEO) and poly(methylmethacrylate) (PMMA). These two are vinyl-type polymers having similar skeletal chain cross-sections. The subject of the present study is the physical characterization of blends of PEO and hydroxypropyl cellulose (HPC). While the studies on PE0/PMMA blends involved melt blending or nonaqueous solutions, in the present case, both PEO and HPC are water soluble. In addition, the skeletal chain cross-sections of PEO and HPC differ appreciably.Aqueous solution of PEO and HPC (1% wt/v) were prepared. Blends of varying composition were made from these solution by mixing for one hour using a magnetic stirrer.
