Title (EN) THERMOLATENT CATALYST AND ITS USE IN CURABLE COMPOSITIONS
(FR) CATALYSEUR THERMOLATENT ET SON UTILISATION DANS DES COMPOSITIONS DURCISSABLES
Abstract:
(EN) Tin-containing catalysts are provided comprising a compound of formula I. L1, L2, L3, and L4 are each independently selected from -O-, -S-, -OC(=O)-, -OC(=S)-, -SC(=O)-, -SC(=S)-, -OS(=O)2O-, -OS(=O)2- -N(R6)-, and -OP(=O)(R6)-, wherein R6 represents hydrogen or a monovalent aliphatic, araliphatic, cycloaliphatic or aromatic group having up to 20 carbon atoms. R1, R2, R3, R1', R2', and R3' each independently represent a divalent aliphatic, araliphatic, cycloaliphatic or aromatic group having up to 20 carbon atoms; and R4, R5, R4', and R5' each independently represent hydrogen or a monovalent residue derived from reaction of a respective N-H group with an isocyanate, an ethylenically unsaturated compound, a lactone, a dilactone, a thiolactone, a lactam, a thiolactam, a carboxylic acid or derivative thereof, or an epoxide. Also provided are curable compositions containing these catalysts and methods of controlling the rate of cure of curable compositions.
(FR) L'invention concerne des catalyseurs contenant de l'étain comprenant un composé de formule I. L1, L2, L3, et L4 sont chacun indépendamment choisis parmi -O-, -S-, -OC(=O)-, -OC(=S)-, -SC(=O)-, -SC(=S)-, -OS(=O)2O-, -OS(=O)2- -N(R6)-, et -OP(=O)(R6)-, où R6 représente un atome d'hydrogène ou un groupe aliphatique, araliphatique, cycloaliphatique ou aromatique monovalent ayant jusqu'à 20 atomes de carbone. R1, R2, R3, R1 ', R2 ', et R3'représentent chacun indépendamment un groupe aliphatique, araliphatique, cycloaliphatique ou aromatique divalent ayant jusqu'à 20 atomes de carbone; et R4, R5, R4 ', et R5' représentent chacun indépendamment un atome d'hydrogène ou un résidu monovalent dérivé de la réaction d'un groupe N-H respectif avec un isocyanate, un composé à insaturation éthylénique, une lactone, une dilactone, une thiolactone, un lactame, un thiolactame, un acide carboxylique ou un dérivé de celui-ci, ou un époxyde. L'invention concerne également des compositions durcissables contenant ces catalyseurs et des procédés de régulation de la vitesse de durcissement de compositions durcissables.
