Abstract
A process for preparation of modified polyolefin particles which comprises contacting and reacting (A) 100 wt. parts of polyolefin particles with (B) 0.01 to 50 wt. parts of at least one ethylenic unsaturated compound selected from the group consisting of carboxyl group-containing ethylenic un-saturated compounds or their carboxylic anhydrides or their carboxylic acid derivatives, hydroxyl group-containing ethylenic unsaturated compounds, amino-group-containing ethylenic unsaturated compounds, and glycidyl group-containing ethylenic unsaturated compounds, in the presence of (C) more than 10 wt. parts to not more than 50 wt, parts of a medium of a liquid state at ordinary temperature whose solubility in water at 20 °C is 0.5 wt. % or less and which is capable of swelling the polyolefin, and (D) 0.01 to 10 wt. parts of a radical initiator; and modified polyolefin particles prepared by the aforesaid process.
