Claim:
1. A curable sealant composition, comprising: a resealable, swellable, reactive sealant and free radical initiator, said resealable, swellable, reactive sealant comprising i) from about 50 to about 90 wt. % of a monofunctional monomer susceptible to only one free radical reaction; ii) from about 5 to about 50 wt. % of a multifunctional monomer having multiple species susceptible to free radical reaction; iii) from about 1 to about 15 wt. % reactive unsaturated polymer; iv) from about 1 to about 15 wt. % of a swellable additive; and v) from 0 to about 10 wt. % of other optional components, based on the total wt. of all components i to iv, totaling 100 wt. %, wherein upon curing the composition, when contacted with oil and/or water, swells by equal to or greater than 15% of the weight of the composition prior to contact with the oil and/or water.
