摘要： A blend of multimodal average molecular weight sulfur or ether linkage containing organic polymers provides sealants, potting compounds and moldable compositions with good physical properties. In the case of S-containing polythioether or polysulfide, these properties are well suited to the formulation of aerospace sealants even using standard lightweight filler technology. Sealants based upon this multimodal blend concept exhibit improved strength and toughness even when relatively large amounts of lightweight fillers are used. Multimodal polyurethanes and other ether linkage containing polymers also show enhanced physical properties.
