    摘要： The present invention provides amphipathic graft copolymers which comprises a hydrophobic polymer portion to which is grafted at least one amphipathic polymer portion containing pH independent ionic groups. The amphipathic graft copolymers can be prepared employing a procedure which comprises polymerizing at least two hydrophobic monomers, wherein at least one of the monomers is a graftable monomer, and at least one hydrophilic monomer, including at least one anionic and/or cationic pH independent ionic monomer, or a post reactive non-ionic monomer that can be converted to a pH independent ionic derivative, in a reaction medium and recovering the thus prepared amphipathic graft copolymer. Stable, substantially non-aqueous solution compositions of said amphipathic graft copolymer containing less than 15 percent by weight water are also provided. The present invention is also useful in preparing a substantially non-aqueous concentrate formulation of a non-ionic surfactant and an amphipathic graft copolymer composition in admixture with a water insoluble organic pesticide which concentrate formulation can be easily diluted with water to form non-settling, freeze-thaw stable formulations.

    摘要： A stable copolymer dispersion is prepared by addition copolymerization of (1) a monomeric adduct of an active hydrogen compound, e.g., a polyether polyol or polyether monool, and an ethylenically unsaturated N-chlorosulfonyl carbamyl compound such as acryloxyethylchlorosulfonylcarbamate or an unsaturated N-chlorocarbonyl carbamyl compound with (2) ethylenically unsaturated monomer(s), e.g., styrene or a mixture thereof with acrylonitrile, while (1) and (2) are dispersed or dissolved in an excess of an active hydrogen polyfunctional compound such as a polyether polyol. The molar ratio of carbamyl moiety to active hydrogen compound is preferably less than about 0.1:1. The resulting dispersion has a controlled particle size and a viscosity such that it is suitably employed in the production of polyurethane foams.
