A blenda PVC/PCL é importante quanto a suas propriedades mecânicas e biodegradabilidade. Neste trabalho foi analisada a biomodificação da blenda PVC/PCL pré-tratada com calor (130ºC), através da espectroscopia UV-Vis. Os resultados mostraram que o pré-tratamento com calor pode facilitar a biomodificação em filmes de PVC, mas pode inibir a biomodificação nos filmes da blenda PVC/PCL. Studies were carried out on biomodification and the pre-heat (130(0)C) influence on Poly (vinyl chloride) / Poly (epsilon-caprolactone) films. The results showed that heat pre-treatment improved the biomodification of PVC films, but it inhibited the biomodification of the PVC/PCL film.
