Abstract
Residual monomer in a polymer matrix may be reduced by a method including admixing a polymer matrix comprising an amount of residual monomer and a conjugated diene. This method can be carried out under reaction conditions such that the amount of residual monomer is reduced. The monomer comprises at least one electron withdrawing substituent and the conjugated diene comprises at least one electron donating substituent. This method is particularly useful for reducing the amount of residual styrene monomer in polystyrene homopolymer and copolymer compositions.

A method for reducing residual monomer in a polymer matrix comprising admixing a polymer matrix comprising an amount of residual monomer and a conjugated diene under reaction conditions such that the amount of residual monomer is reduced, wherein the monomer comprises at least one electron withdrawing substituent and the conjugated diene comprises at least one strong or moderate electron donating substituent or at least two weak electron donating substituents.
A polymer matrix including an adduct of a conjugated diene and a residual monomer, wherein the monomer comprises at least one electron withdrawing substituent and the conjugated diene comprises at least one strong or moderate electron donating substituent or at least two weak electron donating substituents.
