ABSTRACT:
Use of cellulose fibers of natural origin as an admixture to polyvinyl chloride is disclosed. Structurally modifying a polyvinyl article by admixing cellulose fibers limits heat shrinkage thereof and results in improved surface characteristics and/or mechanical characteristics. A polyvinyl article is provided which is comprised of polyvinyl chloride and from 1 to 40 wt. %, preferably from 3 to 20 wt. %, cellulose fibers having a fiber thickness ranging from a finite thickness to about 40 .mu.m and a fiber length ranging from twice the fiber thickness to about 400 .mu.m, preferably from about 80 .mu.m to about 400 .mu.m.
