Abstract:
1. A water-sensitive elastic film comprising: at least one water-soluble polymer, wherein the water-soluble polymer has a weight average molecular weight of from about 10,000 to about 150,000 grams per mole and a number average molecular weight of from about 1,000 to about 80,000 grams per mole; at least one plasticizer for the water-soluble polymer that includes a polyhydric alcohol, wherein the ratio of the melt viscosity of the olefinic elastomer to the plasticized water-soluble polymer is from about 0.6 to about 2.5, and wherein the weight ratio of the water-soluble polymer to the plasticizer is from about 1 to about 50; and at least one olefinic elastomer, wherein the weight ratio of the water-soluble polymer to the olefinic elastomer is from about 0.01 to about 3.0.
