Synthesis and Characterization of the Grafted PVC Filled with Local Inorganic Resource Underutilized

Abstract

There is the problem of mass disposal of scallop shells as unutilized resource in our Aomori Prefecture. The principal component of shell is calcium carbonate exhibiting hydrophilic property. On the other hand, we have previously developed a new synthetic method of the grafted poly(vinyl chloride) (PVC) improved the giving hydrophilicity by grafting poly(2-methyl-2-oxazoline)s as reported in the preceding paper. Thus this paper describes the preparation of novel grafted PVC composites filled with powder of scallop shell.
