Abstract:
The invention relates to aqueous finely divided polymer dispersions which are film-forming at low temperatures, have good caking properties in a formulation, even at higher temperatures, and have little foaming tendency. The invention also relates to methods for producing said dispersions and to the use thereof as binders for coating substrates.
Abstract:
The present invention provides multistage aqueous polymer dispersions which are film-forming at low temperatures, exhibit good blocking resistance in a formulation, even at elevated temperatures, display low foam propensity, and possess good wet adhesion and shelf life, processes for their preparation, and the use thereof as binders for coating substrates.

Abstract:
Método para preparar una dispersión acuosa de partículas estructuradas a partir de un polímero y de un sólido inorgánico finamente dividido (dispersión acuosa de partículas compuestas), en el que se polimerizan monómeros etilénicamente insaturados divididos de manera dispersa en el medio acuoso y por medio de al menos un iniciador de polimerización por radicales libres en presencia de al menos un sólido inorgánico finamente dividida de manera dispersa y de al menos un agente auxiliar de dispersión según el método de la polimerización en emulsión acuosa por radicales libres caracterizado porque a) se emplea una dispersión acuosa estable de al menos un sólido inorgánico que se caracteriza porque a una concentración inicial de sólido de >= 0,1 % en peso, respecto de la dispersión acuosa de al menos un sólido, incluso una hora después de su preparación contiene en forma dispersada más del 90 % en peso del sólido dispersado originalmente y sus partículas de sólido dispersadas presentan un diámetro = 0,01 y = 90 y = 5 y
Abstract:
The present invention provides a process for preparing emulsion polymer particles of a hollow core/shell structure in the presence of a monomer plasticizer having a ceiling temperature less than 181° C. wherein a polymerization inhibitor or reducing agent is not added to the aqueous emulsion of the core shell particles during the neutralization and swelling stage. The obtained core shell particles are useful in paints, paper coatings, foams, and cosmetics.
