34 Claims

1. An initiator component comprising an alkali metal salt derivative of a mixture of two or more styrene derivatives of Formula (I),

wherein

n is 0 or 1;

R¹and R²are the same or different and represent an alkyl group containing from 1 to 10 carbon atoms, or an aryl or aralkyl group containing from 6 to 10 carbon atoms; and

i) R³and R⁴are the same or different and each R³and R⁴independently represents i) a hydrocarbyl group containing from 1 to 10 carbon atoms, the hydrocarbyl group optionally being interrupted by at least one heteroatom selected from a silicon atom, an oxygen atom or a nitrogen atom; or ii) an aryl or aralkyl group containing from 6 to 10 carbon atoms and optionally at least one heteroatom selected from a silicon atom, an oxygen atom or a nitrogen atom; or

ii) R³and R⁴are bonded to each other to form a heterocyclic ring containing the nitrogen atom and at least one carbon atom and, optionally, at least one heteroatom selected from a silicon atom, an oxygen atom and a nitrogen atom; and

the mixture of the two or more styrene derivatives of Formula (I) comprises (1) para isomer, and (2) meta or ortho isomer of one type of the styrene derivative of Formula (I), wherein in the mixture of the two or more styrene derivatives of Formula (I), the weight ratio of the para isomer to the meta or ortho isomer ranges from 1:9 to 9:1.
