Abstract

Disclosed is an aqueous dispersion which is capable of forming a free-standing, coherent, elastomeric, solid film which, after drying and annealing at 80 °C for 30 minutes, demonstrates a tensile strength of 11.0 MPa or greater wherein the dispersion comprises: I. an organic phase comprising: (a) one or more block copolymer(s) corresponding to the formula A-B-Xm-(B-A)n, wherein each A is a polymer block consisting essentially of a monovinylidene aromatic monomer having a weight average molecular weight from 8,000 to 15,000 Daltons, each B is a polymer block consisting essentially of a conjugated diene and, optionally, a monovinylidene aromatic monomer having a weight average molecular weight average weight from 30,000 to 200,000 Daltons, X is the remnant of a multifunctional coupling agent, m is 0 or 1, and n is an integer from 1 to 5, (b) optionally, an extender for the block copolymer which is compatible with the B block, and (c) an antiozonant selected from the group of dialkyl paraphenylenediamines, acetals and styrene-substituted phenols; II. a surfactant; and III. water, wherein the A block effective phase volume in the organic phase is from 5 to 20 percent. Also disclosed are the films prepared from such dispersions.
