摘要： Sidewalls of a pneumatic tire have greater resistance to failure due to dynamic flexing and abrasion, and the tire's tread has better resistance to tearing than with conventionally used rubber compositions, when sidewalls and tread are formed from a compound having a major proportion by weight of synthetic rubber (SR) and a minor proportion by weight of natural rubber (NR), and a major proportion by weight of the SR itself consists essentially of a high cis-1,4-polybutadiene having defined molecular architecture. The high cis-1,4-PBD has more than 90 percent cis-structure, a poly-dispersity in the range from about 3 to 5, a number average molecular weight Mn in the range from 100,000 to 150,000 and a degree of branching in the range from 2 to 3.5. The sidewall compound has characteristics quite different from one made with a typical commercially available high cis-1,4-PBD; and the tread has excellent tear strength. The dendritic structure of the high HI cis-1,4-PBD molecules has an unexpectedly beneficial effect on the performance characteristics of the sidewall and tread, particularly important in a high-performance automobile tire.

摘要： Hoses are often reinforced with fabric to improve their performance characteristics, such as burst strength. For instance, radiator hose used in automotive applications is generally reinforced with continuous yarn. However, it is a labor-intensive process to manufacture such hoses which include fiber reinforcements. A substantial amount of material waste also generally occurs in the manufacture of such fiber-reinforced hose. By utilizing the technique of this invention, hose which has a high level of burst strength can be manufactured without including continuous yarn reinforcement. This invention specifically reveals a process for manufacturing a hose which comprises (1) extruding a rubber composition into the form of a tube, wherein the rubber composition is comprised of (a) a polypropylene/polyethylene alloy comprised of (i) a low melt index polyethylene and (ii) polypropylene, wherein the polypropylene is homogeneously dispersed throughout the polyethylene in the polypropylene/polyethylene alloy, (b) an EPDM rubber, (c) carbon black, (d) at least one curative, (e) zinc oxide, (f) a processing oil and (g) stearic acid; (2) shaping the tube into the geometric form desired for the hose; and (3) curing the rubber composition at a temperature within the range of 130.degree. C. to 210.degree. C. to produce the hose.
