ERODIBLE POLYMERS AND PAINTS FOR FOULING CONTROL ABSTRACT OF THE INVENTION The present invention relates to a novel polymeric binder for use in an antifouling paint which includes a toxicant. The polymeric binder is film-forming, water insoluble, seawater erodible and is represented by the formula Image wherein, in one embodiment, X is H or CH3; M is from greater than 2.5 to less than 25 mole percent of a saturated residue of a tributyltin acrylate or methacrylate group; R is a substantially non-bioactive, substituted alkyl, aryl or arylalkyl moiety; and recurring groups B, where B is the residue of an ethylenically unsaturated monomer. The polymer has a hydrolysis rate of at least 5X10-4 milliequivalents per hour. The resultant paint has an erosion rate of at least 2 microns per month. R can be selected from the group consisting of: a) Image or Image wherein Z is NO2, halogen or CN; V is H, NO2, halogen, CN, alkoxy; b) -(CH2)nY wherein n is an integer from 1 to 4; and Y is selected from the group consisting of Image and wherein R' is C1 to C4 primary, secondary or tertiary alkyl, R" is H or R'; R''' is alkyl or an aryl; c) can be -SiR3''' or -Si(OR''')3; d) R can be a haloalkyl group having at least one trihalo- methyl group where the halogen is Br, F, C1, and the alkyl has at least two carbon, e.g. trifluoroethyl acrylate; e) a quaternized aminoalkyl represented by the formula Image where Y is Br, C1 or I, R', R" and R''' are the same or different C1 to C18 alkyls.
