1. A composition which comprises a mixture comprising at least about 95 wt % of two or more adducts and one or more oligomers, which individual adducts and oligomer(s) of these mixtures can be represented by the formula:
Ar—CH2[—CH2CR(Ar′)]n—CH2CHR—Ar′wherein Ar and each Ar′ are phenyl groups,each R is a hydrogen atom, n is a whole number in the range of 0 to 24 and wherein said composition has a polydispersity in the range of 1.1 to about 3.0, a standard deviation in the range of 60 to 2100 Daltons, and an asymmetry in the range of 1.763 to 4.13. |
