US7125934B1 Functionalization of living rubbery polymers
This invention discloses a low cost process that can be used to functionalize living rubbery polymers with terminal nitroxide end-groups to promote interaction between the polymer end-groups and surface functionalities commonly found on carbon black and silica fillers. Such functionalization makes the rubbery polymer more desirable for used in tire tread
Over the product life cycle, antioxidants [such as PPDs, TMQs (2,2,4-trimethyl-1,2-dihydroquinoline), and phenolics] are designed to diffuse to tire rubber surfaces, rapidly scavenge ground-level atmospheric ozone and other reactive oxidant species, and form protective films to prevent ozone-mediated oxidation of structurally important rubber

Purpose The purpose of this paper is to study the effect of new heterocyclic compounds on styrene butadiene rubber (SBR) mixes. Design/methodology/approach It has been found that the starting material 1 could react with cyromazine (2) and/or 4‐aminoantipyriene (4) as amino compounds in the presence of triethylorthoformate and in the boiling dioxane to
