Abstract
Compositions de polymères aromatiques monovinyliques ayant une capacité de fusion élevée et de bonnes propriétés thermiques et d'écoulement les rendant propres aux applications de moulage par injection rapide, de moulage par soufflage et de thermoformage. Elles sont constituées de polymères et copolymères aromatiques monovinyliques non linéaires possédant des structures en peigne à 3 ramifications, des structures en étoile de 4 à 6 ramifications, et/ou des structures dendritiques dont les ramifications comportent elles-mêmes d'autres éléments ramifiés. Ces compositions possèdent une capacité de fusion intrinsèque et peuvent être moulées par soufflage ou thermoformées sans défectuosités ou moulées en articles dans des temps de cycle plus courts, et ceci en utilisant moins de matières que les polymères et copolymères aromatiques monovinyliques linéaires ayant les mêmes points d'écoulement et de déformation à chaud. L'invention porte également sur un procédé de fabrication à des débits élevés de polymères aromatiques monovinyliques ramifiés de masse moléculaire élevée, par exemple, entre 75.000 et 500.000, qui consiste à polymériser du styrolène pur ou du styrolène et du comonomère que l'on peut polymériser par procédé de polymérisation radicalaire continue en utilisant un amorceur au peroxyde comme, par exemple, le n-butyl tert-butyl peroxy fumarate, sélectionné à partir d'une nouvelle classe d'amorceurs au peroxyde vinylique qui comprennent à la fois une double liaison copolymérisable et une fraction de peroxyde organique.
