Styrene - an overview | ScienceDirect Topics
The effect of the sulfur accelerator ratio on the cross-link distribution in SBR is similar to NR. In general, a lower sulfur level and a higher accelerator level are normally employed for SBR cure systems. Emulsion polymerized SBRs are used alone, as well when as blended with butadiene or natural rubber.

Piperidine
Piperidine is a widely used secondary amine. It is widely used to convert ketones to enamines. Enamines derived from piperidine can be used in the Stork enamine alkylation reaction. Upon treatment with calcium hypochlorite, piperidine convert to N-chloropiperidine, the chloramine with the formula C 5 H 10 NCl.

Vulcanization - an overview | ScienceDirect Topics
Increasing this ratio progressively favors shorter crosslinks. This can be alternatively accomplished by using sulfur donors in place of most or all of the elemental sulfur for vulcanization. The thiuram accelerators, particularly the disulfides, and dithiodimorpholine are commonly used for this purpose.
