Abstract: Aqueous solutions of adhesive materials which can be easily filtered and deodorized, particularly for self-adhesive labels, with a solids content of over 65 % can be produced with good reproducibility of characteristics through copolymerization of esters of acrylic and/or methacrylic acid in the presence of less than 50 ppm inhibitor and preferabl y in the presence of 0.01 to 5 % by weight of reducing agents, according to a special emulsion process. The highly concentrated and steam- deodorized adhesive material dispersion is free of coagulants and specks.

Abstract: LA PRESENTE INVENCION TRATA DE UN PROCEDIMIENTO PARA LA RETIRADA DE RESIDUOS VOLATILES DE DISPERSIONES POLIMERICAS, REALIZANDOSE PRIMERO UNA DESODORIZACION QUIMICA UTILIZANDO UN INICIADOR PARA RETIRAR LOS MONOMEROS RESIDUALES, Y A CONTINUACION UNA DESODORIZACION FISICA PARA RETIRAR LOS COMPONENTES VOLATILES, REALIZANDOSE LA DESODORIZACION QUIMICA DURANTE TANTO TIEMPO, HASTA QUE LA RETIRADA DE MONOMEROS SEA MAS FUERTE QUE LA ADICION DE LOS COMPONENTES SECUNDARIOS QUE SE INTRODUCEN EN LA DISPERSION MEDIANTE EL INICIADOR. EL PROCEDIMIENTO DE LA INVENCION DA UNA MANERA SEGURA DISPERSIONES POLIMERICAS CON UN CONTENIDO EN RESIDUOS VOLATILES DE

Abstract: Readily filterable and deodorizable aqueous dispersions of pressure-sensitive adhesive, especially for self-adhesive labels, having solids contents of more than 65%, can be prepared with readily reproducible properties by copolymerizing esters of acrylic and/or methacrylic acid in the presence of less than 50 ppm of inhibitor and, preferably, in the presence of from 0.01 to 5% by weight of reducing agent by a special emulsion technique. The highly concentrated pressure-sensitive adhesive dispersion, subsequently deodorized with steam, is free from coagulum and seediness.
