In order to obtain a new family of acrylic organotitanium polymers which could be of major interest in the field of non-toxic, self-polishing, antifouling coatings, five acrylic organotitanium monomers, three of which are new, were synthesised. They were analysed by n.m.r. and FTi.r. spectroscopy as well as by microanalysis. Their main features were studied from a structural point of view. The presence of one to three types of structure was shown. The results were linked to the influence of the steric hindrance of the alkoxy groups attached to the titanium atom.
