Abstract:
The present invention relates to a process for the preparation of branched polyolefins having pending polar functionalities via the copolymerization of first an olefin monomer and second an olefin monomer comprising a main group metal hydrocarbyl functionality agent. The invention moreover relates to branched polyolefin having short chain branches with polar functionalities.

Claim (Index 1):
A process for the preparation of a polyolefin having one or more pending polar functionalities, said process comprising the step of:\n A) a polymerization step comprising copolymerizing at least one first type of olefin monomer and at least one second type of olefin monomer comprising a main group metal hydrocarbyl functionality according to Formula 1a:\n R 100 (n-2) R 101 M n+ R 102 \u2003\u2003(Formula 1a) \n using a catalyst system to obtain a polyolefin; wherein said catalyst system comprises a catalyst or catalyst precursor comprising a metal from Group 3-10 of the IUPAC Periodic Table of elements that does not lead to chain transfer polymerization with the main group metal hydrocarbyl functionality of the second type of olefin monomer, and\n wherein further M is a main group metal; n is the oxidation state of M; R 100 , R 101  and R 102  of Formula 1a are each independently selected from the group consisting of a hydride, a C1-C18 hydrocarbyl group, or a hydrocarbyl group Q with the proviso that at least one of R 100 , R 101  and R 102  is a hydrocarbyl group Q, wherein hydrocarbyl group Q is according to Formula 1b: \n wherein Z is bonded to M and Z is a C1-C18 hydrocarbyl group; R 105  optionally forms a cyclic group with Z; wherein R 103  and R 104  and R 105  are each independently selected from hydrogen or a hydrocarbyl group; and at least one of the steps of: B) an oxidizing step comprising contacting said polyolefin obtained in step A) with at least one oxidizing agent to obtain a polyolefin having one or more pending oxidized functionalities; and/or C) contacting said polyolefin obtained in step A or step B) with at least one quenching agent to obtain a polyolefin having one or more pending polar functionalities.
