Abstract

A process of polymerizingwherein the stoichiometric ratio of (f+g)≈(h+i) and f, g, h and i are not equal to 0. Additionally, R1, R2, R3 and R4 can be independently selected from the group consisting of alkyl group, alkoxy group, aryl groups and combinations thereof and where the combination of R1, R2, R3 and R4 are not all identical. In addition, x and y can be different from each other and independently selected from the group consisting of: alkyl group, alkoxy group, aryl groups,where y=1-3,where y=0-12,where R5 is selected from the group consisting of H, alkyl group, alkoxy group, aryl groups,where R6 is selected from the group consisting of H, alkyl group, alkoxy group, aryl groups,where R7 and R8 are independently selected from the group consisting of H, alkyl group, alkoxy group, aryl groups, —NR9R10 where R9 and R10 are independently selected from the group consisting of H, alkyl group, alkoxy group, aryl groups.
