Claims18
An aqueous suspension concentrate containing between about 20 and about 90 wt. % active hydrophobic material;
- between about 0.1 and about 15 wt. % of a copolymeric, anionic dispersing agent and between about 0.1 and about 10 wt. % of a homopolymer and/or a copolymer of a heterocyclic vinyl lactam containing 4 to 6 ring carbon atoms;
- which heterocyclic polymer is optionally substituted on the ring or in the vinyl moiety with lower alkyl.
