Title (EN) POLYETHYLENE NAPHTHALATE POLYESTER POLYOL AND RIGID POLYURETHANE FOAMS OBTAINED THEREFROM
(FR) POLYESTER POLYOL DE POLYETHYLENE NAPHTALATE ET MOUSSES RIGIDES DE POLYURETHANE OBTENUES A L'AIDE DE CETTE SUBSTANCE
Abstract: front page image
(EN)Process for preparing a poly(alkylene polyaromatic dicarboxylate)ester based polyester polyol comprising the steps of a) depolymerising poly(alkylene polyaromatic dicarboxylate) in the presence of a glycol and b) transesterifying the obtained product by addition of polycarboxylic acids, anhydrides or esters and/or polyhydric alcohols and use of the thus obtained polyester polyol in the manufacture of rigid polyurethane and urethane-modified polyisocyanurate foams.
(FR)Ce procédé de préparation d'un polyester polyol à base de poly(alkylène polyaromatique dicarboxylate)ester consiste, (a) à dépolymériser le poly(alkylène polyaromatique dicarboxylate) en présence d'un glycol et, (b) à transestérifier le produit obtenu par adjonction d'acides polycarboxyliques, d'anhydrides ou d'esters et/ou d'alcools polyhydriques. On utilise le polyester polyol ainsi obtenu pour produire des mousses rigides de polyuréthanne et de polyisocyanurate modifié par de l'uréthanne.
