Composition containing an acrylic resin,a polyethyleneimine,and a polyepoxide

N Vassileff
TLDR
In this paper, a mixture of a POLYACRYRYLIC RESIN with a deterministic deterministic additive additive additive is presented. But the results of the mixing are not available.
Abstract: 
POLYMER COMPOSITIONS SHOWING SELECTIVE PERMEABILITY FOR GAS AND WATER VAPORS ARE PREPARED THROUGH INTIMATE ADMIXTURE OF A POLYACRYLIC RESIN WITH A POLYETHYLENIMINE IN A WEIGHT RATIO OF FROM ABOUT 5:1 TO ABOUT 2:1 RESPECTIVELY, AND CROSS-LINKING THE RESULTANT MIXTURE. THE POLYACRYLIC RESIN IS PEDOMINANTLY COMPOSED OF MONOMER UNSATURATED MONOMERS SUCH AS ACRYLIC, ACID, METHACRYLIC UNSATURATED MONOMERS SUCH AS ACRYLIC, ACID, METHACRYLIC ACID, ITACONIC ACID, THE ESTERS THEREOF, THE AMIDES THREOF AND THE NITRILES THEREOF. THE POLYETHYLENIMINE CAN BE UNSUBSTITUTED OR SUBSTITUTED ON THE IMINE GROUP BY ALKYL, HYDROXYLALKYL, HYDROXYCHLOROALKYL, HYDROXYSULFOALKYL, EPOXYALKYL, PHENYLALKYL, CYANOALKYL OR CARBAMYL GROUPS. AT LEAST THE POLYETHYLENIMIBNE COMPONENT OF THE COMPOSITION IS CROSS-LINKED, EITHER INTERNALLHY THROUGH THE USE OF AN AGENT SUCH AS ZINC AMMONIUM CARBONATE OR THROUGH ADDITION OF A CROSS-LINKING AGENT SUCH AS AN EPOXIDE.

Anti-fouling overcoating composition and use thereof

Charles F. De Long
TL;DR: An anti-fouling overcoating composition for watercraft or stationary underwater structures precoated with hard surface leaching-type anti fouling paint consists essentially of an aqueous solution or dispersion of a carboxylated hydrophilic acrylic copolymer, a cross-linking agent for the carboxymethylene glycol, a polyalkylenepolyamine derivative and an effective amount of an ultraviolet absorbing agent as mentioned in this paper.
