“…O estado de mistura do sistema PVC/ NBR está diretamente relacionado ao teor de acrilonitrila da borracha nitrílica. Segundo a literatura [19][20][21] , verifica-se que o grau de miscibilidade aumenta com o teor de acrilonitrila na NBR até um teor ótimo a partir da qual se observa o comprometimento das propriedades mecânicas, gerando blendas Para a blenda PVC/NBR (70/30) vulcanizada in situ estudada observou-se dois valores de Tg (34 e 54 °C), os valores obtidos estão mais próximos do que as demais blendas estudadas, porém o sistema também pode ser considerado imiscível. Já para a blenda PVC/NBR (70/30) convencional observou-se que os valores da Tg (14 e 50 °C) estão se aproximando porém em menor intensidade.…”

Resumo: Vulcanização dinâmica é o processo de vulcanização de um elastômero durante a mistura no estado fundido com um termoplástico, que resulta em uma classe de materiais denominada termoplásticos vulcanizados. Neste trabalho, um novo tipo de termoplástico vulcanizado foi obtido por vulcanização dinâmica in situ da blenda PVC/NBR, utilizando-se um sistema de cura a base de enxofre (S) e combinação dos aceleradores 2,2-ditiomercaptobenzotiazol (MBTS) e dissulfeto de tetrametiltiuram (TMTD). As blendas PVC/NBR (90/10, 80/20 e 70/30% em massa) foram processadas em um reômetro de torque Haake (Rheomix 600) a 160 °C com rotação de 60 rpm. As blendas obtidas por processamento reativo foram caracterizadas por calorimetria diferencial de varredura (DSC) para determinação do grau de cura. Observou-se aumento no grau de cura das blendas com o tempo de mistura sendo o sistema de cura considerado eficiente.

PVC/NBR Blends by Reactive Processing I: In situ Dynamic Vulcanization ProcessAbstract: Dynamic vulcanization is a process of vulcanization of an elastomer during melt mixing with a thermoplastic wich results in material called thermoplastic vulcanizates or TPVs. In this study, a new kind of TPV was obtained by in situ dynamic curing of poly(vinyl chloride) (PVC)/nitrile rubber (NBR) blends. The crosslinking of PVC/NBR blends was accomplished using sulphur (S)/tetramethylthiuram disulphide (TMTD) and mercaptobenzthiazyl disulphide (MBTS) curative system during the reactive processing. The blends of PVC/NBR at the ratio of 90/10; 80/20 and 70/30 wt. (%) were melt mixed using a Haake Rheomix 600 at 160 °C and rotor speed of 60 rpm. The curing behavior of NBR was investigated by a Monsanto Rheometer and the degree of cure was calculated using differential scanning calorimetry (DSC) for different mixing times. It was observed that the degree of cure increases with the mixing time and the crosslinking system used in this work was considered efficient.

ABSTRACT:A modified method is discussed that is based on Farooque and Deshpande's method to obtain polymerpolymer interaction parameters using inverse gas chromatography (IGC) data. In the Farooque and Deshpande method, the ratio of the difference of probe-polymer interaction parameters between two polymers and the probe volume [( 12 Ϫ 13 )/V 1 ] is used as the abscissa. In the modified method, the ratio [( 2 12 ϩ 3 13 )/V 1 ] is used as the abscissa. Experimental data previously reported for a poly(⑀-caprolactone)-polyepichlorohydrin (PCL/PECH) blend and a poly(ethyl acrylate)-poly(vinyl propionate) (PEA/PVPr) blend are analyzed. It is found that the slopes obtained by the new method had smaller deviations from the theoretical values than the Farooque and Deshpande method. The standard deviations of both slopes and intercepts obtained from the new method are also smaller. Using the new method, the polymer-polymer interaction parameters obtained from the intercept are negative numbers for the PCL/PECH system and very small positive numbers for PEA/PVPr. Explanations are given for the probe and concentration dependency of the polymer-polymer interaction parameters that are generally observed in IGC studies. A new method for selecting the best probe for calculating the interaction parameter is discussed.
