    • An improved process for bonding natural or synthetic fibers to elastomeric copolymers of ethylene and higher alpha-olefins or to terpolymers of ethylene, higher alpha-olefins and cyclic or acyclic dienes having non-conjugated double bonds is disclosed. The process comprises coating the fibers with an aqueous dispersion of phenol-aldehyde resin and a latex of an elastomeric ethylene copolymer or terpolymer as defined above which is grafted with an acid, water-soluble vinyl or vinylidene monomer, the aqueous dispersion having been allowed to mature for from 10 to 80 hours after preparation thereof. After the fibers are coated with the aqueous dispersion and dried, an elastomeric ethylene copolymer or terpolymer as defined above and containing a vulcanizing agent is contacted therewith and vulcanized thereon.
    • 公开了将天然或合成纤维与乙烯和高级α-烯烃的弹性共聚物或乙烯,高级α-烯烃和具有非共轭双键的环状或非环状二烯的三元共聚物结合的改进方法。 该方法包括用酚醛树脂的水性分散体和如上所述的弹性体乙烯共聚物或三元共聚物的胶乳涂覆纤维,该胶乳用酸,水溶性乙烯基或亚乙烯基单体接枝,水分散体已经被允许 其制备后10〜80小时成熟。 在用水分散体涂覆纤维并干燥后,将如上所述含有硫化剂的弹性体乙烯共聚物或三元共聚物与其硫化并硫化。
