AbstractA carboxylic elastomer based on butadiene, styrene, and methacrylic acid was polymerized and neutralized to form an ionomeric network I. Sequential IPNs were formed by synthesizingin situpolystyrene crosslinked with divinylbenzene as network II. Annealing studies were carried out, with and without reacidification, to ascertain the role played by ionic crosslinks in influencing morphology and mechanical behavior. Finally, the product is reneutralized, resulting in are arranged, relaxed structure. Ionic crosslinks in polymer I provide anin situdecrosslinking mechanism which permits molecular rearrangements to be induced. By annealing the material, a more cocontinuous phase morphology with concomitant modulus increases is attained. This investigation suggests an alternative method of inducing dual phase continuity in multipolymer combinations.
