“…The blends showed negative deviation from the additivity line for all compositions. The negative deviations from the line indicate the poor interactions between the phases and interlayer slippage that occurs between phases 40,41 . However, among the blends the 60PEO/40SIS exhibited near values to additivity line, which may be attributed to improved interaction due to co‐continuous morphology causing the increment in viscosity 42 …”

Thermally-triggered shape memory polymers (SMPs) are smart materials, which are capable of changing their shapes when they are exposed a heat stimulant. Blending semi-crystalline and elastomeric polymers is an easy and low-cost way to obtain thermo-responsive SMPs. In this work, novel poly(ethylene-co-1-octene) (PEO) and poly(styrene-b-isoprene-b-styrene) (SIS) thermoplastic elastomer blends were prepared via melt blending method. The morphological, mechanical, rheological properties and shape memory behaviours of the blends were investigated in detail. In morphological analysis, co-continuous morphology was found for 50 wt% PEO/50 wt% SIS and 60 wt% PEO/40 wt% SIS (60PEO/40SIS) blends. The shape memory analysis per

“…Grafting of MA onto non-polar polymers increases the hydrophilicity of the polymer surface. Therefore, the maleated polymer can be used as a main component in a reactive blending process [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. The grafting of MA onto NR has been commonly done in the molten state by using shearing action in the presence or absence of peroxide.…”

The direct incorporation of ground tire rubber (GTR) as a waste rubber into a virgin polymer matrix causes a remarkable reduction in its mechanical and performance properties. In this work, maleic anhydridegrafted natural rubber (MA-g-NR) was employed as a compatibilizer to improve the interaction between a natural rubber (NR) matrix and GTR. The effect of MA-g-NR on curing characteristics, rheological behavior, morphology, and performance properties of the NR-GTR blend was studied using an oscillating disk rheometer, rheomechanical spectroscopy (RMS), scanning electron microcopy (SEM), and tensile and abrasion testing. The obtained results by RMS and SEM tests revealed better adhesion between NR and GTR in the presence of MA-g-NR. Using up to 8 parts of MA-g-NR caused an increase in the curing rate index, and a remarkable increase in mechanical properties and abrasion resistance was observed, which was comparable to or even better than the virgin vulcanizate.

SYNOPSISThe effect of prevulcanization on the rheological behavior of natural rubber (NR), styrene butadiene rubber (SBR) latices, and their blends was studied with special reference to shear rate, blend ratio, vulcanizing systems, prevulcanization time, and accelerator systems. The NR latex showed a sharp increase in viscosity with increase in prevulcanization time due to high extent of crosslinking. However, SBR latex showed marginal effect on viscosity with prevulcanization time due to its low dry rubber content and low degree of unsaturation. Blends showed variations in viscosity according to the change in composition. The use of a single accelerator was found to have marked influence on the viscosity of the blends compared with a combination of accelerators. Swelling experiments were carried out in order to determine the crosslink density of the blends. The viscosity changes have been correlated with the crosslinking density of the latices and their blends. 0 1996 John Wiley & Sons, Inc.
