Abstract
"COMPOSIçãO E PROCESSO PAPA PRODUZIR ELASTÈMERO DE POLIURETANO". Uma composição é divulgada para produzir um elastómero usando pré-polímeros de diisocianato de tolueno. A composição é preparada misturando (a) poliisocianato, (b) componente curativo e (c) um catalisador consistindo essencialmente de 1,8-diazabiciclo(5,4,0 )undec-7-eno; onde o poliisocianato compreendendo pelo menos 70 por cento em peso da composição contendo isocianato é um pré-polímero terminado em diisocianato de tolueno contendo menos que cerca de 2 por cento em peso de monómero de diisocianato de tolueno livre e o componente curativo contém compostos tendo grupos reativos com isocianato, onde pelo menos 40 por cento em peso dos compostos tendo grupos reativos com isocianato são compostos tendo pelo menos um grupo hidroxila."Composition and Process to Produce Polyurethane Elastomer". A composition is disclosed to produce an elastomer using toluene diisocyanate prepolymers. The composition is prepared by mixing (a) polyisocyanate, (b) curative component and (c) a catalyst consisting essentially of 1,8-diazabicyclo (5,4,0) undec-7-ene; wherein the polyisocyanate comprising at least 70 weight percent of the isocyanate-containing composition is a toluene diisocyanate-terminated prepolymer containing less than about 2 weight percent of free toluene diisocyanate monomer and the curative component contains compounds having groups isocyanate-reactive compounds, where at least 40 percent by weight of compounds having isocyanate-reactive groups are compounds having at least one hydroxyl group.
