In the preceding article, allyl benzoate (ABz) was copolymerized with diallyl terephthalate (DAT) in the presence of poly(benzyl methacrylate) [poly(BzMA)] having different molecular weights, with the aim to discuss further the significance of the thermodynamic excluded volume effect on gelation in free-radical monovinyl/divinyl crosslinking copolymerizations as a primary factor for the greatly delayed gelation from Flory–Stockmayer theory. In the present article, the above copolymerization proceeded to a late stage of polymerization, i.e., beyond the gel-point conversion, in order to study the incorporation of poly(BzMA) as a chemically inactive, linear polymer into ABz–DAT network formed, providing the basic data for molecular-designing the vinyl type semiinterpenetrating polymer network (semi-IPN).
