A method for bonding a fabric to a polyolefin elastomer. The method comprises applying to the fabric: (a) from 10 to 90 wt % of an aqueous dispersion of a thermoplastic polymer; and (b) from 90 to 10 wt % of an aqueous dispersion of a rosin, wherein percentages are based on total dry weight of thermoplastic polymer and rosin.

An adhesive composition contains a block copolymer hot melt adhesive and a vapor releasing vapor corrosion inhibitor mixed with the block copolymer hot melt adhesive, the vapor corrosion inhibitor being in the form of particles suspended in the adhesive composition, the particles preferably having a maximum dimension of less than about 30 microns. One improvement results from inclusion in the adhesive mixture of a titanium and/or zirconium containing coupling agent, either separately or as part of the VCI particles. Another improvement results from blending the adhesive mixture in a continuous process using for example a twin screw extruder. As a result, the adhesive mixture has better uniformity and superior viscosity properties during use.

A structural adhesive bond formed with a pressure-sensitive adhesive that comprises at least two components forming one phase each, from which an interpenetrating network with at least two phases is produced by a cross-linking build-up reaction, the first phase and second phase having at least a softening point temperature of less than 23° C. and greater than 23° C., respectively, the two phases having a morphology of a cross-linked nanoparticle network after the build-up reaction.

Modified thermoplastic hydrocarbon thermoplastic resins are provided, as well as methods of their manufacture and uses thereof in rubber compositions. The modified thermoplastic resins are modified by decreasing the relative quantity of the dimer, trimer, tetramer, and pentamer oligomers as compared to the corresponding unmodified thermoplastic resin polymers, resulting in a product that exhibits a greater shift in the glass transition temperature of the elastomer(s) used in tire formulations. This translates to better viscoelastic predictors of tire tread performance, such as wet grip and rolling resistance. The modified thermoplastic resins impart remarkable properties on various rubber compositions, such as tires, belts, hoses, brakes, and the like. Automobile tires incorporating the modified thermoplastic resins are shown to possess excellent results in balancing the properties of rolling resistance, tire wear, snow performance, and wet braking performance.
