Abstract:
Provided herein are cured rubber compositions containing guayule natural rubber with 2.5-4 weight % resin and fillers. By the use of a specified cure package that contains increased amounts of sulfur and accelerator, the cured rubber compositions are found to exhibit strain induced crystallization (as can be observed by X-ray diffraction). Also provided are related methods for preparing the rubber compositions.

Claim (Index 8):
A method of providing a cured guayule natural rubber containing composition with strain induced crystallization comprising:\n a. utilizing a rubber mixture that comprises (i) either 100 phr of guayule natural rubber that contains 2.5-4 weight % resin, or a combination of 10-90 phr of guayule natural rubber that contains 2.5-4 weight % resin and 90-10 phr of at least one conjugated diene monomer containing polymer or copolymer, and (ii) 5-100 phr of at least one filler selected from the group consisting of carbon black and silica, and b. utilizing a cure package comprising (i) 1.2 to 4 phr sulfur, (ii) 0.5 to 5 phr of at least one antioxidant, (iii) 0.5 to 5 phr zinc oxide, (iv) 0.5 to 4 phr stearic acid, (iv) 1.05 to 3 phr of at least one accelerator to produce a cured guayule natural rubber containing composition wherein the cured guayule natural rubber containing composition exhibits strain induced crystallization (as evidenced by X-ray diffraction).
