... 1356563 Pressure-sensitive adhesive coated fabric EVODE Ltd 2 Aug 1971 [27 Aug 1970] 41285/70 Heading B2E A pressure-sensitive adhesive laminate comprises a layer of a pressure-sensitive adhesive composition coated onto a backing sheet comprising a self-bonded, non-woven polyamide fabric. The latter may be formed by heat fusion of a mat of nylon strands at their crossover points. The adhesive layer is preferably thicker than the polyamide fabric, and is preferably a bituminous composition, containing a thermoplastic polymer or a natural or synthetic rubber. Other constituents of the adhesive include flux oil, petroleum resins and fillers, e.g. SiO 2 . The adhesive may be applied to the fabric so that little impregnation occurs or alternatively it may partially or fully impregnate the fabric such that it strikes through onto the outer surface. A hopper may be used to deliver the adhesive between fabric and release paper, a calender machine situated downstream serving to spread the adhesive ...

IMPROVING THE ADHESION BETWEEN RUBBER COMPONENTS

IMPROVING THE ADHESION BETWEEN RUBBER COMPONENTS The process of this invention can be utilized to improve the adhesion between rubber components. It is generally most useful for improving the adhesion between two different pre-cured rubber components or for improving the adhesion between a pre-cured rubber component and an uncured (green) rubber component. However, the technique of this invention can also be employed to improve the adhesion between two uncured rubber components. The technique of this invention is based upon the unexpected discovery that low molecular weight trans-1,4-polybutadiene containing rubber compounds can be used to improve the adhesion between rubber components. This invention more specifically reveals a technique for improving the adhesion between a first rubber component and a second rubber component in a process for manufacturing a cured rubber article, said technique comprising the steps of: (1) positioning a layer of an adhesion-promoting rubber composition ...

Asphalt compositions and methods of making same

A coupled block copolymer composition with a combination of high viscosity at manufacturing, finishing and handling conditions, low viscosity at asphalt blending conditions and suitable viscosity stability is provided for use in asphalt compositions. The composition comprises: (i) a diblock copolymer, (ii) at least a linear triblock copolymer having a peak molecular weight that is 1.5 to 3.0 times the peak molecular weight of the diblock copolymer, and (iii) at least a multiarm coupled block copolymer having a peak molecular weight that is 1.5 to 9.0 times the peak molecular weight of the diblock copolymer, and mixtures thereof. The block copolymer composition is characterized as having a melt viscosity at 110°C or less of greater than 2.0E7 Poise and a coupling efficiency after 24 hours at 180°C is less than 25%.

Modified resins and uses thereof

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.
