Substituted azo-dicarbonylo derivatives

摘要

This invention relates to novel azo-dicarbonylo derivatives of a C3-C4 olefin polymers of the formula ##STR1## These can be prepared by reacting an ene compound such as a polypropylene or a polybutene, especially those with a vinylidene group, with an enophile such as X--CO-- NN--CO--Y. The resultant products can be used either as such or after further functionalization with eg polyamines as an additive for fuels and lubricants.
