                    Abstract: With the continuous growth of car ownership, the market's demand for tire appearance is
                increasing day by day. Especially for the sidewall of tires, due to long-term exposure to the environment and
                extreme weather conditions, higher requirements are placed on the performance of sidewall formulations.
                This article focuses on the influence of internal release agents on the performance of sidewall formulations
                and product appearance.The results showed that the Mooney viscosity (M L ) of rubber compound decreased
                and the maximum torque (M H ) and elongation at break increased with the addition of internal release agent.
                Although it does not significantly affect the machining performance of finished tires, the use of internal release
                agents can cause problems such as redness in the appearance of the product. In addition, canceling the use
                of internal release agents can effectively reduce the production cost of this formula.
                    Key words: semi steel radial tire; internal release agent; appearance
                                                                                                          (R-03)

                    近日,中国科学院兰州化学物理研究所低碳催化与二氧化碳利用全国重点实验室在聚碳酸酯合成催化剂制备
                领域取得重要进展,研究人员成功研发出聚碳酸酯合成用高性能催化剂。
                    该催化剂在国内相关企业 26 万 t/ 年的聚碳酸酯生产装置上进行工业化应用,成功生产出合格的聚碳酸酯产品。
                    据了解,聚碳酸酯是一种重要的含羰高分子材料,具有优良的物理和化学性质,广泛应用于电子电器、汽车、
                建筑、机械等领域。传统的聚碳酸酯合成方法主要依赖于光气法,经由甲醇氧化羰基化制碳酸二甲酯、酯交换制
                碳酸二苯酯,进而合成聚碳酸酯是当今和未来聚碳酸酯产业的绿色环保路线。该项技术为我国聚碳酸酯产业的绿
                色发展和转型升级提供了强有力的技术支撑。
