Abstract
This invention provides adducts, mixtures of adducts and oligomers, and/or mixtures of adducts, oligomers, and low molecular weight polymers formed from monovinylaromatic hydrocarbons.
Claims18
A composition which comprises
- a mixture comprising 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, independently, aromatic hydrocarbon moieties, 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 1.32 to 1.64, a standard deviation in the range of 174 to 471 Daltons, and an asymmetry in the range of 1.763 to 4.13.
