Abstract
The kinetics of polystyrene (PS) accumulation in polyvinylidene fluoride (PVDF) films as a result of the thermal polymerization of styrene sorbed from a styrene-toluene-divinylbenzene solution at 90°C was studied. After accumulation of ∼65 wt % PS in the sample, the thermal polymerization rate increased by approximately an order of magnitude. This was explained by an increase in the volume of the nanosized PS phase saturated with the monomer from the surrounding solution. The thermal polymerization of styrene in the PVDF matrix proceeded in the formed nanoreactors at a constant monomer concentration in them. The rate of thermal polymerization of styrene in the PVDF film was an order of magnitude higher than that in the surrounding solution. The initiation of styrene polymerization at the interface between PVDF and monomer-saturated PS nanoinclusions was assumed to be heterogeneous.
