摘要： The green strength of synthetic elastomers is improved by forming interpolymers from at least one type of various synthetic elastomer forming monomers with an epoxy containing monomer having the formula: ##STR1## where R.sub.1 contains from 0 to 8 carbon atoms and R.sub.2 contains from 1 to 4 carbon atoms. Typical elastomer forming monomers include at least one conjugated diene having from 4 to 10 carbon atoms, olefins having from 2 to 14 carbon atoms along with a diene having from 4 to 6 carbon atoms, and combinations thereof. The interpolymer preferably is blended with synthetic elastomers or natural rubber (cis-1,4-polyisoprene) and utilized for various industrial uses such as tire carcasses including radial truck tire carcasses. The green strength is further improved if a small amount of an epoxy cross-linking agent is utilized. Examples of suitable cross-linking agents include monoamines and polyamines, monoanhydrides and polyanhydrides, and monocarboxylic acids, as well as polycarboxylic acids. Desirably, the interpolymer of the synthetic elastomer forming monomer and the epoxy containing monomer is blended with various types of synthetic elastomers or natural rubber in the presence of an epoxy cross-linking agent in a suitable mixing vessel such as a Banbury.
摘要翻译：合成弹性体的生坯强度通过从至少一种类型的各种合成弹性体形成单体与具有下式的含环氧基的单体形成共聚物得到改进：其中R 1含有0至8个碳原子，R 2含有 1至4个碳原子。典型的弹性体形成单体包括至少一种具有4至10个碳原子的共轭二烯，具有2至14个碳原子的烯烃以及具有4至6个碳原子的二烯及其组合。共聚物优选与合成弹性体或天然橡胶（顺式-1,4-聚异戊二烯）共混，并用于各种工业用途，例如轮胎胎体，包括径向卡车轮胎胎体。如果使用少量的环氧交联剂，则生坯强度进一步提高。合适的交联剂的实例包括单胺和多胺，一元酸酐和聚酐，以及一元羧酸以及多元羧酸。理想的是，合成弹性体形成单体和含环氧基的单体的互聚物在各种类型的合成弹性体或天然橡胶中在环氧交联剂的存在下在合适的混合容器如Banbury中混合。
