A synthetic process comprising the following steps: providing a reaction mixture comprising: an ethylenically unsaturated anhydride monomer, at least one ethylenically unsaturated non-anhydride monomer, a free radical initiator, and an alkyl substituted THF solvent having the general structure of formula 1:
1
where R

4
linear or branched alkyl with the proviso that at least one of R
