NEUTRAL BATH DYEING OF POLYOLEFINS WITH ACID DYES

摘要

A method of dyeing a grafted hydrocarbon polymer containing at least one polymerizable terminal olefin with an acid dye in the pH range of about 6 to about 7 which comprises the steps of quaternizing the grafted polymer with a dialkyl sulfate and contacting the resulting material with an acid dye at a pH of about 6 to about 7.
