摘要

通过元素硫和硫醚（苯乙烯硫醚和环己烯硫醚）的阴离子共聚得到了硫含量可变且可控的硫化物聚合物，并将其用作丁苯橡胶硫化过程中的固化剂（硫供体）。根据硫化过程的流变测量结果和利用动力学数据计算的硫化参数，研究了多硫化物作为硫化剂的活性。研究了在静态和动态条件下与硫化胶机械性能相关的交联密度和结构。研究了多硫化物作为二烯橡胶交联剂的整体适用性。

VULCANIZATION OF STYRENE–BUTADIENE RUBBER WITH THE USE OF POLYSULFIDE SULFUR DONORS OF CONTROLLED STRUCTURE

The sulfide polymers of variable and controlled sulfur content, obtained by anionic copolymerization of elemental sulfur and thiiranes (styrene sulfide and cyclohexene sulfide), were applied as curatives (sulfur donors) in the vulcanization process of styrene–butadiene rubber. The activity of polysulfides as curatives was investigated based on rheometric measurements of the vulcanization process and calculations of curing parameters using kinetic data. The crosslink density and structure related to the mechanical properties of the vulcanizates under static and dynamic conditions were studied. The overall suitability of polysulfides as crosslinking agents for diene rubbers was investigated.
