    • A catalyst composition and process for preparing norbornene-type homopolymers or copolymers. The norbornene-type homopolymers or copolymers can be prepared using an in-situ catalyst composition including: (a) a transition metal compound of ML4, wherein M is a Group 10 metal and L is a neutral electron donor ligand; (b) a hydrocarbyl halogen containing a double bond or a triple bond; and (c) a salt of a non or weakly coordinative anion that can replace a halogen bonded to a metal. The catalyst composition is in a mixing state of components (a), (b), and (c), or in a mixing state of a reaction product of components (a) and (b) together with component (c).
    • 催化剂组合物和制备降冰片烯型均聚物或共聚物的方法。 降冰片烯型均聚物或共聚物可以使用原位催化剂组合物制备,包括:(a)ML4的过渡金属化合物,其中M是第10族金属,L是中性电子给体配体; (b)含有双键或三键的烃基卤素; 和(c)可以取代与金属键合的卤素的非配位或弱配位阴离子的盐。 催化剂组合物处于组分(a),(b)和(c)的混合状态,或组分(a)和(b)的反应产物与组分(c)的混合状态。
