Abstract
(EN)
Polymeric foams having nanocellular morphology are formed from a polymeric material having structural units derived from 2-hydrocarbyl-3,3- bis(hydroxyphenyl)phthalimidine compound. The foams include a plurality of cells having an average diameter of less than 1 micron. Processes for forming the foams include melting a polymeric material having structural units derived from 2- hydrocarbyl-3,3-bis(hydroxyphenyl)phthalimidine compounds; diffusing a blowing agent into the polymeric material to form a mixture; nucleating bubbles in the mixture is at a sufficient temperature and pressure to enable the production of cells having an average diameter of less than 1 micron; stabilizing the cells; and forming the mixture into a desired shape.

L'invention concerne des mousses polymériques ayant une morphologie alvéolaire de taille nanométrique formées à partir d'une matière polymérique ayant des unités de structure dérivées d'un composé 2-hydrocarbyl-3,3-bis(hydroxyphényl)phtalimidine. Les mousses comprennent une pluralité d'alvéoles ayant un diamètre moyen inférieur à 1 micron. L'invention concerne également des procédés servant à former les mousses consistant à faire fondre une matière polymérique ayant des unités de structure dérivées de composés 2-hydrocarbyl-3,3-bis(hydroxyphényl)phtalimidines ; faire diffuser un agent d'expansion dans la matière polymérique pour former un mélange ; faire nucléer des bulles dans le mélange à une température et une pression suffisantes pour permettre la production d'alvéoles ayant un diamètre moyen inférieur à 1 micron ; stabiliser les alvéoles ; et mettre le mélange sous une forme souhaitée.
