Patent ID: 6894134

Claim:
A process for the production of a polyolefin having at least 50 branches per 1000 methylene groups and at least two branches of different lengths containing less than 6 carbon atoms each, comprising the step of polymerizing one or more monomers of the formula H 2 C═CH(CH 2 ) e G, wherein G is hydrogen or —CO 2 R 1 , e is 0 or an integer of 1 to 20, R 1 is hydrogen, hydrocarbyl or substituted hydrocarbyl, and in at least 50 mole percent of said monomers G is hydrogen, by contacting said one or more monomers with a transition metal containing coordination polymerization catalyst under polymerizing conditions such that in said polyolefin: (i) the number of branches per 1000 methylene groups is 90% or less than the number of theoretical branches per 1000 methylene groups, or (ii) the number of branches per 1000 methylene groups is 110% or more of theoretical branches per 1000 methylene groups; or (iii) when there should be no branches theoretically present, said polyolefin has 50 or more branches per 1000 methylene groups.
