Title (EN) MICROCAPSULES
(FR) MICROCAPSULES
Abstract:
(EN) The present invention relates to microcapsules comprising a core within a polymeric shell, wherein the polymeric shell comprises a copolymer formed from 50 to 99.9%, by weight of the polymeric shell, of a first shell monomer which is ethylenically unsaturated and which has more than one ethylenic double bond; 0.01 to 50%, by weight of the polymeric shell, of a second shell monomer which is ethylenically unsaturated and which has one ethylenic double bond; and optionally, 0 to 30%, by weight of the polymeric shell, of one or more other shell monomers. The core of the microcapsules comprises an active substance, particularly a phase change material (PCM). The polymeric shell forms less than 8wt% of the total weight of the microcapsules.
(FR) La présente invention concerne des microcapsules comprenant un noyau dans une enveloppe polymère, l'enveloppe polymère comprenant un copolymère formé de 50 à 99,9 %, en poids de l'enveloppe polymère, d'un premier monomère d'enveloppe qui est éthyléniquement insaturé et qui présente plus d'une double liaison éthylénique ; 0,01 à 50 %, en poids de l'enveloppe polymère, d'un second monomère d'enveloppe qui est éthyléniquement insaturé et qui présente une double liaison éthylénique ; et éventuellement 0 à 30 %, en poids de l'enveloppe polymère, d'un ou plusieurs autres monomères d'enveloppe. Le noyau des microcapsules comprend une substance active, en particulier un matériau à changement de phase (PCM). L'enveloppe polymère forme moins de 8 % en poids du poids total des microcapsules.
