Abstract
Abstract Water-borne pollutants, particularly those of oelaginous nature, may be treated with monomers which polymerize in the presence of moisture, preferably, monomeric esters of 2-cyanoacrylic acid. Upon polymerization, significant portions of the pollutant are incorporated within a polymer matrix, thus reducing the danger to shore and marine ecology and aesthetics.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
62 words
A PROCESS FOR REDUCING THE MENACE OF A FLOATING WATERBORNE POLLUTANT WHICH COMPRISES APPLYING TO AT LEAST A PORTION OF SUCH POLLUTANT A LIQUID COMPOSITION CONTAINING A POLYMERIZABLE MONOMERIC OR OLIGOMERIC ESTER OF 2-CYANOACRYLIC ACID OR SOLUTON THEREOF, SAID ESTER POLYMERIZING AFTER CONTACT WITH SAID POLLUTAT TO FORM A SOLID MATRIX WITH INCORPORATION THEREIN OF AT LEAST A PORTION OF SAID POLLUTANT.
Claim 2
Dependent Claim
62 words
A PROCESS FOR REDUCING THE MENACE OF A FLOATING WATERBORNE POLLUTANT WHICH COMPRISES APPLYING TO AT LEAST A PORTION OF SUCH POLLUTANT A LIQUID COMPOSITION CONTAINING A POLYMERIZABLE MONOMERIC OR OLIGOMERIC ESTER OF 2-CYANOACRYLIC ACID OR SOLUTON THEREOF, SAID ESTER POLYMERIZING AFTER CONTACT WITH SAID POLLUTAT TO FORM A SOLID MATRIX WITH INCORPORATION THEREIN OF AT LEAST A PORTION OF SAID POLLUTANT.
Claim 3
Dependent Claim
12 words
The process of claim 1, wherein the pollutant is an oleaginous material.
Claim 4
Dependent Claim
31 words
The process of claim 1 wherein the ester of 2-cyanoacrylic acid has the formula CH2 C(CN)-COOR wherein R is a C1 16 alkyl or alkenyl, a cyclohexyl or a phenyl group.
Claim 5
Dependent Claim
11 words
The process of claim 3 wherein R is a C1-C6 group.
Claim 6
Dependent Claim
43 words
The process of claim 4 wherein the ester of 2-cyanoacrylic acid has the formula CH2 C(CN)-COOR wherein R is a C1 16 alkyl or alkenyl, a cyclohexyl or a phenyl group, and is in a solvent of a liquid hydrocarbon or halogenated hydrocarbon.
Claim 7
Dependent Claim
12 words
The process of claim 3 wherein R is a C1-C4 alkyl group.
Claim 8
Dependent Claim
22 words
The process of claim 1 wherein the composition comprises a mixture of a polymerizable ester of 2-cyanoacrylic acid and a solvent therefor.
Claim 9
Dependent Claim
27 words
The process of claim 7 wherein the solvent comprises from about 10% to about 80% by weight of the mixture of solvent and ester of 2-cyanoacrylic acid.
Claim 10
Dependent Claim
16 words
The process of claim 1 wherein the composition is applied to the pollutant by spraying thereon.
Claim 11
Dependent Claim
21 words
The process of claim 1 wherein the matrix has a density which is less than the specific gravity of the water.
Claim 12
Dependent Claim
16 words
The process of claim 1 wherein the matrix is subsequently removed from contact with the water.
Claim 13
Dependent Claim
65 words
A process for reducing the menace of a floating water-borne pollutant which comprises applying to at least a portion of such pollutant a liquid composition containing a monomeric or oligomeric polymerizable ester of 2-cyanoacrylic acid or solution thereof, said ester diffusing at least partially into said pollutant and thereafter polymerizing to form a matrix with incorporation therein of at least a portion of said pollutant.
Claim 14
Dependent Claim
65 words
A process for reducing the menace of a floating water-borne pollutant which comprises applying to at least a portion of such pollutant a liquid composition containing a monomeric or oligomeric polymerizable ester of 2-cyanoacrylic acid or solution thereof, said ester diffusing at least partially into said pollutant and thereafter polymerizing to form a matrix with incorporation therein of at least a portion of said pollutant.
