Abstract:

A multi-stage aqueous emulsion-polymer suitable for use in dirt pickup resistant coatings and coatings containing the polymer are provided. The multi-stage aqueous emulsion polymer includes (i) a first polymer including at least one nonionic copolymerized monoethylenically unsaturated monomer, from 0. 5% to 7% of a copolymerized monoethylenically unsaturated ionic monomer, based on the weight of the first polymer, and from 0% to 1. 0%, based on the weight of the first polymer, of a copolymerized multi-ethylenically unsaturated monomer, the first polymer having a Tg of 15. degree. C. to 105. degree. C. ; and (ii) a second polymer comprising at least one nonionic copolymerized monoethylenically unsaturated monomer, from 0% to 2% of a copolymerized monoethylenically unsaturated ionic monomer, and from 0. 25% to 6%, based on the weight of the second polymer, copolymerized multi-ethylenically unsaturated monomer, the second polymer having a Tg of -55. degree. C. to 30. degree. C. , the second polymer having a different composition than the first copolymer, and the second polymer being from 25% to 75% of the total weight of the first polymer and the second polymer, based on dry polymer weights.

International Classification:

A01N 4714
A01N 5502
A01N 2512

US Classification:

514476

Abstract:

Novel and improved fungicidal dithiocarbamate particulate compositions comprising one or more components selected from dithiocarbamates and bisdithiocarbamoyl disulfides and an effective amount of moisture content to significantly enhance the flowability of the particulate composition, reduce the dustiness of the composition, increase the bulk density of the composition and/or reduce the ethylenethiourea content of the composition. Methods for producing such particulate compositions are presented wherein controlled slurry production and spray-drying are effective in producing such compositions.
