Abstract

A study was conducted to find out the dimension of a hyperbranched polymer (HBP) synthesized from a N,N-diethylamino dithiocarbamoylmethylstyrene (DCS) derivatives by one-pot reaction and photopolymerization. Dynamic light scattering (DLS) measurement was used for HBP to obtain the hydrodynamic radius, which was larger than linear PS with the same degree of polymerization. The study compared the chain dimension of the HBP, in tetrahydrofuran (THF) and methyl ethyl ketone (MEK)with linear PS. The study found that phenyl ring attached the polymer chain as the side group for PS and for the HBP the phenylene ring was attached into the main chain. The study stated that solvent qualities of MEK and cyclohexane were worse for the HBP than for PS. HBP formed a tiny amount of aggregates at concentrations of 10^-2 g/cm ³ for THF and MEK.
