Title (EN) POLYSTYRENE AND POLYLACTIC ACID BLENDS
(FR) MÉLANGES DE POLYSTYRÈNE ET DE POLYACIDE LACTIQUE
(PT) BLENDAS DE POLIESTIRENO E POLI ÁCIDO LÁTICO
Abstract: front page image
(EN) The invention describes polymeric blends of polystyrene (PS) and polylactic acid (PLA) to which a compatibilising agent is added, preferably a PS-PLA block copolymer. The compatibilising agents have the effect of controlling phase separation between the blend components, preventing excessive growth of the polystyrene domains dispersed in the PLA matrix, leading to the production of blends having satisfactory thermal and mechanical resistance.
(FR) L'invention concerne des mélanges polymères de polystyrène (PS) et de polyacide lactique (PLA) auxquels a été ajouté un agent de compatibilité, de préférence un copolymère bloc PS-PLA. Ces agents de compatibilité agissent en régulant la séparation de phases entre les constituants du mélange, empêchant une croissance excessive des domaines de polystyrène dispersés dans la matrice de PLA, d'où l'obtention de mélanges présentant une bonne résistance thermique et mécanique.
(PT) São descritas blendas poliméricas de poliestireno (PS) e poli ácido lático (PLA) tendo adicionado um agente compatibilizante, preferencialmente um copolímero em bloco PS-PLA. Tais agentes compatibilizantes atuam controlando a separação de fases entre os componentes da blenda, não permitindo crescimento excessivo dos domínios de poliestireno dispersos na matriz de PLA, levando a obtenção de blendas com boa resistência térmica e mecânica.
