  The present invention is a method of incorporating a water insoluble organic chemical into a styrene-butadiene rubber latex dispersion and the resulting styrene-butadiene rubber latex dispersion. A styrene-butadiene rubber latex dispersion is provided comprising an aqueous phase and a disperse phase, with the disperse phase including particles of styrene-butadiene rubber. An organic solvent that is miscible in water and the water insoluble organic chemical are added together to the styrene-butadiene rubber latex dispersion. The addition of the water-miscible organic solvent allows the water insoluble organic chemical to pass from the aqueous phase into the disperse phase thus limiting separation of the water insoluble organic chemical from the latex dispersion. The resulting SBR latex has increased properties over conventional latices that use the same amount of the water insoluble organic chemical but that do not include the water-miscible organic solvent.

  本发明是一种将不溶于水的有机化学品掺入丁苯橡胶胶乳分散体和所得丁苯橡胶胶乳分散体的方法。丁苯橡胶胶乳分散体包括水相和分散相，分散相包括丁苯橡胶颗粒。水溶性有机溶剂和不溶于水的有机化学品一起加入到丁苯橡胶胶乳分散体中。水溶性有机溶剂的加入可使水不溶性有机化学品从水相进入分散相，从而限制水不溶性有机化学品从胶乳分散体中分离出来。与使用相同数量的水不溶性有机化学品但不包括水混溶有机溶剂的传统胶乳相比，所得 SBR 胶乳具有更高的性能。
