摘要： 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.

摘要： The process of the present invention for removing residual volatiles from polymer dispersions by performing first chemical deodorization using an initiator to remove residual monomers and then physical deodorization to remove volatile constituents comprises conducting the chemical deodorization for as long as the decrease in monomers is greater than the increase in secondary components introduced into the dispersion by the initiator, to result reliably in polymer dispersions having a residual volatiles content of less than or equal to 100 ppm.
