    摘要： This invention relates to a farm tire, especially a farm tractor drive tire, with a tread having a running surface of significantly spaced apart lugs designed to be soil engaging of a rubber composition comprised of at least one conjugated diene-based elastomer which contains an organosilane polysulfide in situ coupled dispersion of reinforcing filler as a pre-formed starch/plasticizer complexed composite. The running surface of the farm tire tread itself is of a configuration comprised of widely spaced apart raised lugs to provide a ratio of net running surface of the tread lugs to the tread's gross dimensions (net to gross ratio expressed in terms of percentage of the running surface of the lugs) in a range of from 15 percent to 20 percent. Therefore, operationally in the field, normally few lugs actually touch, or engage, the ground at any one time. Accordingly, such individual tread lugs are desirably capable of experiencing locally high loads and should be sufficiently stiff to resist extensive elongations.

    摘要： The present invention is based upon the finding that lignin can be incorporated into wire coat stock composition to improve metal to rubber adhesion. It has been further found that lignin can be used as a replacement in whole or in part for conventional rubber-to-metal adhesion promoters, such as cobalt materials which are conventionally used in wire coat stocks to attain and maintain needed rubber-to-wire adhesion properties. In fact, wire coat stocks that contain lignin provide more that adequate rubber-to-metal adhesion characteristics for typical applications, such as in tires, and maintain needed levels of adhesion over long periods of product service. The utilization of lignin in wire coat stock formulations in accordance with this invention is also economically advantageous since lignin is a low cost alternative to most conventional adhesion promoting agents. The present invention more specifically discloses a wire coat stock composition which comprises a rubbery polymer, 40 phr to 80 phr of carbon black, and 2 phr to 30 phr of lignin.

    摘要翻译： 本发明基于如下发现：木质素可以结合到线涂料组合物中以改善金属与橡胶的粘附。 进一步发现，木质素可以全部或部分用作常规橡胶 - 金属粘合促进剂的替代物，例如常规用于丝线涂料中的钴材料以获得并保持所需的橡胶对线 粘附性能。 事实上，含有木质素的丝线涂料可为典型应用（如轮胎）提供更好的橡胶 - 金属粘附特性，并在长期的产品服务中保持所需的粘合水平。 根据本发明的线涂料配方中木质素的利用也是经济上有利的，因为木质素是大多数常规粘合促进剂的低成本替代物。 本发明更具体地公开了一种线涂料组合物，其包含橡胶状聚合物，40phr至80phr的炭黑和2phr至30phr的木质素。

    摘要： A pneumatic tire having a radially outer circumferential rubber tread (2), a carcass (5) and a layered composite (6) of at least one sealant layer (7) and at least one air permeation resistant film layer (8) is disclosed. The layered composite (6) comprises a sealant layer (7) on its radially outer side positioned adjacent to the carcass (5). The sealant layer (7) supports an air permeation resistant film layer (8) on its radially inner surface. The sealant layer (7) comprises an organoperoxide depolymerized butyl rubber, or a polyurethane. The air permeation resistant film layer (8) comprises a thermoplastic material containing a dispersion of elastomer domains wherein the thermoplastic material comprises nylon and wherein the elastomer domains comprise at least one of butyl rubber and sulfur curable diene-based elastomer domains.
