1. An elastomeric material comprising:

  • a triblock copolymer of the general configuration A-B-A, a plasticizer, and a bleed-reducing additive;

    wherein A is selected from the group consisting of monoalkenylarene polymers;

    wherein B is an elastomeric polymer;

    wherein said plasticizer associates with said polymer B;

    wherein said triblock copolymer has a measurable percent elongation at break;

    wherein said plasticizer tends to increase the percent elongation at break of said triblock copolymer;

    wherein said triblock copolymer has a rigidity measurable on the Gram Bloom scale; and

    wherein said plasticizer tends to decrease the Gram Bloom rigidity of said triblock copolymer.
