摘要： The invention relates to a curable sealant composition broadly comprising a resealable, swellable, reactive sealant and free radical initiator; said resealable, swellable reactive sealant comprises monofunctional monomer(s), multifunctional monomer(s), reactive polymer such as unsaturated styrenic block copolymer, swellable additive, and optional components. The monofunctional monomer is a vinyl ester derivative of versatic acid with C9-C12 carbon atoms, or monoacrylate, monomethacrylate, monoacrylamide, or monomethacrylamide. The multifunctional monomer are di-, tri-, tetra-, and/or penta-functional monomers with vinyl, acrylate, methacrylate, acrylamide, or methacrylamide functionality, such as tricyclodecane dimethanol diacrylate, trimethylolpropane trimethacrylate, 1,3-butylene glycol dimethacrylate or a mixture thereof. The reactive unsaturated polymer is a styrenic block copolymer such as SBS, SIS, S-I/B-S, I-SEBS-I, and mixtures of two or more of these. The swellable additive is selected from saturated block copolymers such as SEBS, SEPS, SEEPS, and I-SEBS-I, or a mixture of these. Free radical initiators are preferably peroxides, although others are acceptable.
