Vinyl-Divinyl Copolymerization: Copolymerization and Network Formation from Styrene and p- and m-Divinylbenzene

摘要: Abstract The composition of copolymers p- and m-divinylbenzene with styrene was determined by infrared spectrometry during copolymerization compared values calculated on the assumption that polymerizing system is homogeneous, reactivities both vinyl groups in monomers pendant are independent extent copolymerization. At lower conversions content all divinylbenzene units, especially copolymer, than calculated, whereas at higher a fraction does not react. gel point do depend concentration divinylbenzene; percentages divinyl monomer or dilution they for m-divinylbenzene, although p-divinylbenzene contain more units same conversion. deviations explained inhomogeneous caused locally different conc...
