“…[17][18][19][20] Our results suggest considering the solvent uptake as a three-step sequence that confirms this view. First, rubber particles swell while some fluid remains that lubricates the flow into the mixer cavity.…”

ABSTRACT:The solvent uptake by vulcanized rubber particles was studied through a swelling technique by using a torque rheometer to record torque versus time curves, with good repeatability. Several experiments were performed to study the effects of varying the solvent/rubber ratio, the solvent type, and the rubber nature. The effects of the materials alone were also studied. A four-parameter mathematical model was developed, with a physical significance assigned to each of the parameters, and was compared with experiments. The model was found to fit well with the experimental results, therefore, allowing the physical processes involved in the solvent swelling of rubber particles to be investigated through model parameters.

“…The role of various fillers on the diffusion phenomenon through polymers has been addressed by several researchers . Lawandy and Wassef studied the effects of concentration and particle size of carbon black on diffusion process of engine oil through chloroprene rubber/carbon black composites. The results showed that there is direct relation between particle size and diffusion rate.…”

The present paper addresses the usefulness of a sorption gravimetric technique to assess of the compatibility and reinforcing effect of nanofiller against hazardous liquid media. The reinforcing capability of organoclay (Cloisite 30B) in chlorosulfonated polyethylene (CSM) was characterized by means of transport properties such as diffusion, sorption and permeation coefficients, activation energy, enthalpy, and entropy. The CSM/organoclay nanocomposites were prepared by melt mixing method. The transport of toluene through CSM vulcanizates were studied with special reference to the effect of organoclay concentration (0–9 parts per hundred parts of rubber) and temperature (25–55°C). The microstructure of the nanocomposites was confirmed by studying of dispersion of organoclay in CSM via transmission and scanning electron microscopy and X‐ray diffraction. The results showed that the swelling properties of nano‐filled CSMs mainly depend on the presence of organoclay and not its concentration and also the formed microstructure. A good relationship was found between the microstructure and swelling properties of CSM nanocomposites. J. VINYL ADDIT. TECHNOL., 23:E40–E50, 2017. © 2016 Society of Plastics Engineers

“…The properties of TiO 2 that makes it good filler for composite materials are good dispersibility in polymer system and good heat stability. Several studies have been made to modify the properties of halo butyl rubber [5][6][7][8][9][10][11][12][13][14][15]. Hendriske et al [5,6] studied the vulcanization of chloro butyl rubber and determined the crosslink densities.…”

The mechanical and thermophysical properties of TiO2‐filled chlorobutyl rubber composites were investigated. These materials exhibited enhanced mechanical properties such as increased modulus, tensile strength, and hardness. The morphology of filler dispersion in the matrix was analyzed by scanning electron microscopy and atomic force microscopy. Moreover, the effect of TiO2 content on the molecular transport of solvents was examined by means of degree of swelling, volume fraction of rubber, penetration rate of solvent, mean diffusion coefficient, etc. A periodic method was used to estimate the thermophysical behavior of samples. It was shown that the thermal conductivity and diffusivity of composites increase with increasing of TiO2 filler content. Finally, the utilization of the material as effective chemical protective clothing against volatile organic chemicals was analyzed. POLYM. COMPOS., 2011. © 2011 Society of Plastics Engineers
