“…PALS technique was successfully used in several uncured and cured elastomers and/or miscible and immiscible elastomer blends (see for example Refs. [4,[19][20][21][22][23][24][25][26][27][28]). Specifically, changes in the v h of these elastomers were externally induced through different parameters, such as preparation and vulcanization conditions as well as mechanical stresses.…”

“…[16] Besides, NBR is a promising material acting as toughening component for many polymers. Some studies on blending of NBR to improve impact strength and toughness were reported; with PVC, [17] PP, [18] and polyamide. [19][20][21] As noted above, many studies have reported blending PBS with various thermoplastic polymers.…”

Summary: Acrylonitrile butadiene rubber (NBR) has been blended into biodegradable Poly(butylene succinate) (PBS). The PBS/NBR blends with ratios of 100/0, 90/10, 80/20, 70/30, 60/40 and 50/50 by weight were prepared in an internal mixer. Dicumyl peroxide (DCP) was used for vulcanization of the NBR phase in the blends. Mechanical properties and thermal stability as well as morphologies of pure PBS, vulcanized NBR and PBS/NBR blends were investigated. The blends provide much higher elongation and impact strength than the pure PBS. The PBS/NBR blend with a ratio of 90/10 shows superior result to toughness, and gives comparable results for modulus and tensile strength at break with respect to the pure PBS. Morphology observation reveals the compatibility of the PBS/NBR blends, especially in the blends with 10-30 wt% NBR content. Moreover, thermogravimetric analysis (TGA) result shows that thermal stability of PBS is enhanced when NBR is added.

“…There are many studies in TPE material development beginning decades ago, including polypropylene/(nitrile rubber), poly(vinyl chloride) (PVC)/NBR, polypropylene/ (ethylene propylene diene monomer), and PVC/epoxidized natural rubber (ENR) [2][3][4][5][6]. The development of research in PVC/ENR blends has been widely explored [7].…”

The effects of dynamic vulcanization on properties of poly(vinyl chloride) (PVC)/epoxidized natural rubber (ENR)/(kenaf core powder) composite were studied. Tensile properties indicated that the strength, elongation at break, and Young's modulus of the composites exhibited an increase for samples with dynamic vulcanization. Morphological analysis using scanning electron microscopy showed the interaction between ENR and PVC. There was no bonding between kenaf core powder and the PVC/ENR matrix owing to the different polarity of both components. Filler agglomerates increased, which leads to an increase of filler‐filler interaction and poor dispersion. Furthermore, swelling index indicated that the composite with dynamic vulcanization shows lower absorption of tolune compared with composites without dynamic vulcanization. J. VINYL ADDIT.
