Abstract:
A polymer blend comprising a blend of component (1) comprising one or more polymers made using a late transition metal catalyst of Formula (I): wherein M is Fe[II], Fe[III], Co[I], Co[II], Co[III], Mn[I], Mn[II], Mn[III], Mn[IV], Ru[II], Ru[[III] or Ru[IV]; X represents an atom or group covalently or ionically bonded to the transition metal M; T is the oxidation state of the transition metal M and b is the valency of the atom or group X; R1, R2, R3, R4, R5, R6 and R7 are independelty selected from hydrogen, halogen, hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl or substituted heterohydrocarbyl; and when any two or more of R1-R7 are hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl or substituted heterohydrocarbyl, said two or more of R1-R7 can be linked to form one or ore cyclic substituents, and component (2) comprising one or more polyolefins made (a) using a free radical polymerisation process, (b) using a polymerisation process catalysed by a Philips supported-chromium oxide catalyst, (c) using a metallocene polymerization catalyst, or (d) using a Ziegler-Natta catalyst, wherein the blend is made by blending together components (1) and (2) in the form of powder or pellets.
