Possibilities of polyamide 12 with poly(vinyl chloride) blends recycling Summary-Blends of poly(vinyl chloride) (PVC) and polyamide 12 (PA 12) were prepared by melt mixing technique in Brabender Plastograph. The samples have been studied by scanning electron microscopy (SEM), dynamic mechanical analysis (DMA), differential scanning calorimetry (DSC) and Charpy impact strength was tested. PVC/PA 12 blends were compatibilized with chlorinated polyethylene (CPE) and investigeted using the same methods. It was shown that such compatibilization is one of the possibilities how to get desired properties starting from brittle and immiscible PVC/PA 12 blends. Key words-poly(vinyl chloride), polyamide, compatibilization, blend. MO¯LIWOOECI RECYKLINGU MIESZANEK POLI(CHLOREK WINYLU)/POLIAMID 12 Streszczenie-Za pomoc¹ plastografu Brabendera przygotowano mieszanki poli(chlorku winylu) (PVC) i poliamidu 12 (PA 12). Otrzymane próbki badano metodami skaningowej mikroskopii elektronowej (SEM) (rys. 2), dynamicznej analizy mechanicznej (DMA) (rys. 3, tabela 1), skaningowej kalorymetrii ró¿nicowej (DSC) (tabela 1) oraz wyznaczono udarnooeae metod¹ Charpy'ego (rys. 1). Za pomoc¹ tych samych metod zbadano zdolnooeae mieszanek PVC/PA 12 do kompatybilizacji za pomoc¹ chlorowanego polietylenu (CPE) (rys. 4-17). Otrzymane wyniki potwierdzi³y mo¿liwooeci uzyskania z kruchych i niemieszalnych uk³adów PVC/PA 12 mieszanek o po¿¹danych w³aoeciwooeciach. S³owa kluczowe: poli(chlorek winylu), poliamid, kompatybilizacja, mieszanina.

“…Blends of butadiene rubbers and other polymers have received wide attention in the literature during the last two decades (4Ϫ19). The role of NBR as a compatibilizer has also been investigated (5). Processing conditions-such as mixing speed, blending time, and temperature-were reported to have a strong influence on the ultimate properties of the blend (6,8,15).…”

In this study, hydrogenated acrylonitrile butadiene rubber (HNBR, ZETPOL-2010L) and nitrile butadiene rubber (NBR, NIPOL-DN4555) were blended at different ratios in a Haake melt blender at 130°C. The HNBR and the NBR were of very similar acrylonitrile content and Mooney viscosity. The melt miscibility and solid-state properties were investigated by rheological, thermal, and mechanical testing and scanning electron microscopy (SEM) techniques. The dynamic viscosity of the blends followed the log-additivity rule, while the flow activation energy closely followed the inverse additivity rule. On the other hand, the storage modulus showed synergistic effects at all compositions, suggesting the presence of emulsion morphology at both ends of the composition range. For the 50/50 HNBR/NBR blend, the SEM micrographs suggest a uniform elongated structure. The thermal analysis showed the presence of two glass transitions, representing the pure components, at all blend ratios, suggesting the absence of segmental miscibility of the blends. The small-strain mechanical properties such as tensile modulus and yield stress followed linear additivity. However, HNBR and HNBR-rich blends were observed to strain harden at a rate higher than that of NBR. Induced crystallization of HNBR was suggested to be the reason for the strain hardening. The different rheological, thermal, and mechanical testing techniques agree in suggesting that the structurally similar HNBR and NBR are not thermodynamically miscible but mechanically compatible.

“…For instance, the presence of compatibilizer is necessary when SBR is blended with polar polymers such as acrylonitrile butadiene rubber (NBR), polyvinyl chloride (PVC), and chloroprene rubber (CR). [21][22][23][24][25][26] Despite the versatile application of XSBR in the production of gloves, water based paints, membranes as well as blends and composites, due to the lack of thorough and comprehensive knowledge in this field, reporting a study has always necessitated giving detailed information concerning the structure, property, and characteristics of this polymer. Therefore, the aim of this study is to fill this important gap by collecting outspread works published concerning this polymer.…”

The present review focuses on the properties and developing applications of carboxylated styrene butadiene rubber (XSBR) as a modified grade of styrene butadiene rubber (SBR). Carboxylated polymers, and particularly carboxylated rubbers, are regarded as a new class of polymers with superior physical and mechanical properties over non-carboxylated counterparts. Upon introducing carboxyl groups, the properties such as elasticity range, strength, compatibility towards functional fillers and polymers, resistance to hydrocarbon solvents enhance and cross-linking by non-sulfur reagents becomes possible. The XSBR latex benefits from excellent mechanical and chemical stability, excellent liquidity, high bond and conjunction strength, high toughness and the strength after molding, low water absorption and air shrinkage, excellent durability, abrasion, oil and corrosion resistance of cement products. Due to the polarity offered by carboxyl groups, fiber, and particulate composites of XSBR exhibit improved physical and mechanical properties. The stable interface created between carboxyl group and the second polymer phase generally results in an enhancement for the host polymer.
