    • Provided is a method for producing a resin composition by melt-kneading a cyclic olefin polymer (A) having a glass transition temperature of from 60 to 200° C. and a flexible polymer (B) having a glass transition temperature of 0° C. or lower, wherein a part of the cyclic olefin polymer (A) is previously melt-kneaded with the flexible polymer (B) and a radical initiator (C) and then the remaining cyclic olefin polymer (A) is added thereto and melt-kneaded. The cyclic olefin polymer (A) is divided into two portions and added separately at two times, and accordingly, the mixture having a crosslinked structure may be diluted with the cyclic olefin polymer (A) not having a crosslinked structure, and the increase in the melt viscosity of the resin composition may be thereby prevented. A composition having good abrasion resistance and good melt shapability can be obtained.
    • 提供一种通过熔融捏合玻璃化转变温度为60-200℃的环烯烃聚合物(A)和玻璃化转变温度为0℃的柔性聚合物(B)来制备树脂组合物的方法。 或更低,其中一部分环烯烃聚合物(A)预先与柔性聚合物(B)熔融捏合和自由基引发剂(C),然后向其中加入剩余的环状烯烃聚合物(A)并熔融捏合 。 环状烯烃聚合物(A)分成两部分,分两次加入,因此可以用不具有交联结构的环状烯烃聚合物(A)稀释交联结构的混合物, 因此可以防止树脂组合物的熔融粘度。 可以获得具有良好的耐磨性和良好的熔融成形性的组合物。
