A method of dissolving a rubber continuously to form a raw material for the production of rubber-modified polymer, by dissolving a rubber in a monomer liquid dissolving the rubber and capable of reacting with the rubber in the presence or absence of a solvent. Pieces of rubber are fed continuously to a dissolution tank to allow the dissolved rubber and the undissolved rubber to coexist in the dissolution tank, wherein the concentration of the dissolved rubber is the concentration at which the feeding to the reactor is made, and the quantity of the undissolved rubber present in the dissolution tank is at most the quantity that prevents pieces of the undissolved rubber from sticking to one another to form larger rubber masses. The time required for dissolution can be shortened, and the size of a dissolution tank can be made smaller, compared with the conventional methods.
一种连续溶解橡胶以形成用于生产橡胶改性聚合物的原材料的方法,其方法是将橡胶溶解在溶解橡胶并能在有或无溶剂的情况下与橡胶发生反应的单体液体中。将橡胶块连续送入溶解槽,使溶解的橡胶和未溶解的橡胶在溶解槽中共存,其中溶解橡胶的浓度为向反应器进料时的浓度,而溶解槽中未溶解橡胶的数量最多为防止未溶解橡胶块相互粘连形成较大橡胶块的数量。与传统方法相比,溶解所需的时间可以缩短,溶解槽的尺寸也可以缩小。
