Title (EN) TACKIFIED POLYDIORGANOSILOXANE OLIGOUREA SEGMENTED COPOLYMERS AND A PROCESS FOR MAKING SAME
(FR) COPOLYMERES SEGMENTES DE POLYDIORGANOSILOXANES ET D'OLIGO-UREE RENDUS COLLANTS, ET PROCEDE DE FABRICATION
Abstract:
(EN) Tackified compositions comprise a curable polydiorganosiloxane oligourea segmented copolymer which has alternating soft polydiorganosiloxane units and hard diisocyanate residues, the diisocyanate residue being the diisocyanate minus the -NCO groups. The units are connected together by urea linkages and the copolymer has end groups that are reactive under free radical or moisture cure conditions, and silicate resin. Also provided are pressure-sensitive adhesives, hot melt adhesives, and vibration damping composites, vibration damping constrained layer constructions, a bi-directional vibration damping constrained layer constructions, vibration damping shaped articles as well as a method of vibrationally damping an article and processes for producing curable vibration damping material.
(FR) La présente invention concerne des compositions rendues collantes, qui comprennent un copolymère segmenté durcissable de polydiorganosiloxane et d'oligo-urée qui possède en alternance des unités molles de polydiorganosiloxane et des résidus durs de diisocyanate, le résidu de diisocyanate étant le diisocyanate moins les groupes -NCO. Les unités sont reliées ensemble par des liaisons d'urée et le copolymère a des groupes d'extrémités qui sont réactifs dans des conditions de durcissement comportant des radicaux libres ou de l'humidité, et de la résine de silicate. L'invention concerne aussi des adhésifs sensibles à la pression, des adhésifs à chaud et des produits composites amortisseurs de vibrations, des constructions amortisseuses de vibrations à couches contraintes, une construction bidirectionnelle amortisseuse de vibrations à couches contraintes, des articles formés amortisseurs de vibrations ainsi qu'un procédé permettant d'amortir les vibrations d'un objet et des procédés de production d'une matière durcissable amortissant les vibrations.
