It performs excellently on the protection of oxidation of rubber which is caused by thermal oxidative aging and catalytic oxidation by metal ions. Rubber antioxidant is mainly used for natural rubber and chloroprene rubber etc. It has excellent effects to the ageing caused by heating and oxygen and has stronger restrained effect to the metallic catalysis and oxidation, it is Suitable for naturat, buna-s, buna-N and chloroprene rubbers. Rubber antioxidant RD has a longer-time remaining of protective effect, because it has a higher molecular weight and has little diffusive loss. So it is suitable for the rubber products used in tropical area. Antioxidant RD production process is not complicated, polymerized only by ordinary materials, but the product contains components of different degree of polymerization of the polymer content of polymer, the proportion of affected Investigated on the Rubber Antioxidant 2,2,4-Trimethyl-1,2-dihydroquinoline Polymer

橡胶抗氧剂2,2,4-三甲基-1,2-二氢喹啉聚合物的研究

对橡胶因热氧化老化和金属离子催化氧化引起的氧化保护性能优异。橡胶防老剂主要用于天然橡胶、氯丁橡胶等，对受热和氧气引起的老化有很好的效果，对金属催化和氧化有较强的抑制作用，适用于naturat、buna-s、buna-N和氯丁橡胶。橡胶防老剂RD由于分子量较高，扩散损失小，因此保护作用持续时间较长。因此适用于热带地区使用的橡胶制品。抗氧剂RD的生产工艺并不复杂，仅由普通材料聚合而成，但产品中含有不同聚合度的聚合物含量的聚合物成分，
