ABSTRACT:
Synthetic wood pulp characterized by the presence of polyolefin fibrids having both film and fiber morphology is disclosed as being useful for the production of paper-like films. Further disclosed is a technique whereby this morphology may be preserved by transferring such fibrids from the refining dispersant into a preservative medium. After again being refined in the preservative medium, the fibrids can be formed directly into paper-like substrate products. More usually, however, they are first dispersed in water to facilitate this casting.
