4-Vinylpyridine in Lubricant Additives
4-Vinylpyridine is used as an intermediate in lubricants.
4-Vinylpyridine is a reactive monomer and once polymerized, the nitrogen is more exposed/accessible than its counterpart, 2-Vinylpyridine. It can be copolymerized with many other monomers, in particular cationic monomers, such as acrylamide, acrylates, and also with other vinyl-based monomers (e.g. styrene). The benefit of the addition of a 6-membered heterocyclic moiety is the increased Van der Waals forces which impart better electrostatic forces to the finished polymer, improving adhesion.
Vinylpyridines provide a unique set of properties to wide range of applications due to good thermal stability, chemical stability, mild basicity, mild pH trigger, and compatibility with most polymerization techniques.
Applications
Lubricant Additives
4-Vinylpyridine finds usage in pour point depressants due to its unique action and viscosity, stability, and compatibility properties. Pour point depressants are used to allow the use of petroleum based mineral oils at lower temperatures.
