    • Provided is a method for manufacturing diene rubbers having excellent color, heat resistance, and transparency, wherein the rubber is used as hot-melt adhesives and is suitable for preparation of impact-resistant polystyrene resin and polystyrene sheets. The method for manufacturing diene rubbers having excellent color, heat resistance, and transparency comprises the steps of: (1) preparing living polymer by subjecting diene-based monomer to anionic polymerization using an alkyl lithium initiator; (2) adding water to the prepared living polymer, and then stirring the admixture to remove activity of living polymer; and (3) adding an antioxidant to 100 parts by weight of the activity-free polymer, wherein the oxidant consists of 0.01-1 parts by weight of octadecyl-3-(3,5-di-t-butyl-4-hydroxyphenyl)propionate represented by the following formula 1, 0.01-1 parts by weight of tris-(2,4-di-t-butylphenyl)phosphate represented by the following formula 2, and 0.01-1 parts by weight of pentaerythrityl tetrakis(3-dodecylthiopropionate).
    • 提供一种具有优异的颜色,耐热性和透明性的二烯橡胶的制造方法,其中橡胶用作热熔粘合剂,并且适用于制备耐冲击聚苯乙烯树脂和聚苯乙烯片材。 制造具有优异的颜色,耐热性和透明性的二烯橡胶的方法包括以下步骤:(1)通过使用烷基锂引发剂使二烯类单体进行阴离子聚合制备活性聚合物; (2)向制备的活性聚合物中加入水,然后搅拌混合物以除去活性聚合物的活性; 和(3)向100重量份的无活性聚合物中加入抗氧化剂,其中氧化剂由0.01-1重量份的十八烷基-3-(3,5-二叔丁基-4-羟基苯基) 由下式1表示的丙酸酯,0.01-1重量份由下式2表示的三(2,4-二叔丁基苯基)磷酸酯和0.01-1重量份季戊四醇四(3-十二烷基硫代丙酸酯) )。
