A process for the production of a foam rubber tree bark-configured article having a manmade textile backing is provided. The inventive process involves the vulcanization of NBR or SBR including a chemical blowing agent, and optionally including EPDM as an ozone-resistance agent, over a silicon-base mold which is a negative relief mold of at least a portion of tree bark, and with a backing adhered to, and not easily removed from, the unmolded side of the rubber. Such a backing is either 100% polyester or 100% nylon, which provides an excellent, long-lasti...


[ What we claim is:] [1.] A method of forming a tree bark-configured rubber article having a manmade textile backing comprising the sequential steps of(a) providing a rubber composition comprisingat least one rubber selected from the group consisting of acrylonitrile-butadiene rubber (NBR), styrene-butadiene rubber (SBR), and mixtures thereof;at least one nitrogen-containing blowing agent;optionally, an ozone-resistance agent being ethylene-propylene-diene (EPDM); andoptionally, at least one other additive selected from the group consisting of an antista...
