Te. Grokhovskaya et al., SPECIFIC FEATURES OF BLOOMING OF LOW-MOLE CULAR-MASS COMPONENT IN (RUBBER POLYMER) (LOW-MOLECULAR-MASS HYDROCARBON) SYSTEMS, Vysokomolekularnye soedinenia. Seria A, 36(6), 1994, pp. 20001016-20001020
The composites based on four rubbers (natural rubber, butadiene rubber
, poly(octyl methacrylate), and silicon rubber) were swollen in octade
cane at 50-degrees-C until equilibrium and then cooled below the cryst
allization temperature of hydrocarbon. The kinetics of blooming of low
-molecular-mass component from the above composites was studied. At a
given temperature, the rates of blooming of low-molecular-mass compone
nt from rubber matrices with similar crossing density were shown to be
primarily controlled by glass transition temperature of the polymer m
atrix: the lower the glass transition temperature, the higher the rate
of blooming of hydrocarbon.
