ABSTRACT:
Polymers containing organotin compounds having advantageous use as paint binders obtained by reacting a cyclized rubber with organotin compounds of the formula R.sub.3 --Sn--O--Z wherein R represents a hydrocarbon group from 1 to 15 carbon atoms and Z is a phenolate group derived from a phenolic compound having from 6 to 15 carbon atoms. In marine applications paints incorporating such polymers remain un-fouled after extended use and are self-polishing. Such polymers are obtained by reacting cyclized rubber and an organotin compound at an elevated temperature in an inert solvent.
