Title (EN) METHOD FOR OBTAINING POLYMERS WITH ISOCYANATE GROUPS
(ES) PROCEDIMIENTO DE OBTENCIÓN DE POLÍMEROS CON GRUPOS ISOCIANATO
(FR) PROCÉDÉ PERMETTANT D'OBTENIR DES POLYMÈRES COMPORTANT DES GROUPES ISOCYANATE
Abstract: front page image
(EN)The invention relates to a method for obtaining polymers bearing isocyanate groups from amino polymers, with both aromatic and aliphatic amines, in a simple manner and under mild conditions. The polymers bearing isocyanate groups can be used as intermediates that react with compounds comprising amine, alcohol, thiol and carboxylic acid groups, in order to obtain polymers with subsequent alterations.
(ES)Procedimiento para obtener polímeros portadores de grupos isocianatos a partir de polímeros aminados, tanto aminas alifáticas como aromáticas, y de manera simple y en condiciones suaves. Estos polímeros portadores de grupos isocianatos pueden ser usados como intermedios reaccionando con compuestos que comprenden grupos amina, alcohol, tioles o ácidos carboxílicos, para obtener polímeros con modificaciones posteriores.
(FR)La présente invention concerne un procédé permettant d’obtenir des polymères porteurs de groupes isocyanate à partir de polymères aminés, aussi bien amines aliphatiques qu’aromatiques, de manière simple et dans des conditions modérées. Ces polymères porteurs de groupes isocyanate peuvent être utilisés comme intermédiaires qui réagissent avec des composés comportant des groupes amine, alcool, tiol ou acide carboxylique, afin d’obtenir des polymères comportant des modifications postérieures.
