<p>Fine particle styrene polymers are coated with 0.05-0.3 wt.% of one or more oxyalkylation products of formula:- H-(O CH2 CHR1)n-)-R2 where R1 is H or max. 30 mole % CH3; and R2 is fatty acid, fatty alcohol, or fatty acid amide, alkylamine, or phenol opt. substd. by alkyl and n is 2-40. Polymer products have reduced residence time in the mould.</p> |
