Abstract

The present invention relates to a process for improving the water wettability of polyolefins, especially under the form of fibers, fibrils or powders. The thus treated polyolefins have an improved wettability, which in the treatment conducted in aqueous suspension facilitates their dispersion in water. This is among others the case in the production of at least partially synthetic papers.
