ABSTRACT Blends of organic-terminated polysulfide polymers and organic polymers are disclosed. The organic polymer may be a saturated organic elastomer, an ethylenically unsaturated organic elastomer, a non-elastomeric polymer, or any combination blend of the three. Said blends exhibit unexpectedly good tensile properties and resilience and are useful for forming gaskets, membranes, sealants, adhesives, hoses, tubing and similar articles. A method of sealing cracks and joints in concrete or asphalt structures is also disclosed. The cracks or joints are sealed with a sealant which is a blend of organic-terminated polysulfides and an organic polymer.
