Brief description of the agglomeration of a latex, latex agglomerated obtained, and the application of a latex polybutadiene thus obtained has the production of resins acrylonitrile butadiene styrene - -

摘要

The agglomeration of a polymer latex selected amongst elastomers and thermoplastic resins is carried out by mixing the latex to be agglomerated with an agglomerating latex comprised of: (A) a polymer selected amongst elastomers and thermoplastic resins; and (B) a non-ionic surfactant consisting of a sequenced polymer comprising at least one polyoxyethylene sequence and at least one polymer sequence selected amongst vinylic, diene polymers of acrylic and methacrylic esters, said agglomerating latex being obtained by the synthesis of the polymer defined under (A) during which (B) has been used as surfactant. Amongst surfactants (B), the trisequenced polymer polyoxyethylene-polystyrene-polyoxyethylene may be mentioned.
