(Q, e) values are cited from Polymer Handbook,52 and reactivity ratios were calculated based on Alfrey-Price equations: r1=(Q1/Q2)·exp[−e1(e1−e2)]; r2=(Q2/Q1)·exp[−e2(e2−e1)].
Individual vinylic functionalities within the divinyl monomer structures. MA: methyl acrylate; BE: 1-butene; MMA: methyl methacrylate; VAc: vinyl acetate; AAc: allyl acetate; MSt: p-methyl styrene; MOSt: p-methoxy styrene.
Both 4-(3-buten-1-yl)-styrene (E) and (3′-buten-1′-oxy) 4-vinylbenzyl ether (F) were approximated to the same copolymerization system as 4-methoxy styrene vs. 1-butene.
4-(3′-Buten-1′-oxy)-2,3,5,6-tetrafluorostyrene (1) was approximated to a copolymer pair of PFS with BE. The (Q, e) of PFS is cited from the literature.55
