Abstract | 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
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 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:
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
and wherein
R min is C1 to C4 primary, secondary or tertiary alkyl,
R sec is H or R min ;
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 trihalomethyl group where the halogen is Br, F, Cl, and the alkyl has at least two carbon, e.g. trifluoroethyl acrylate;
e) a quaternized aminoalkyl represented by the formula
where Y is Br, Cl or I,
R min , R sec and R''' are the same or different C1 to C18 alkyls. |
