Water-borne structure for polymers comes in the context of paints were a basic ingredient is the binder "which is a polymer or resin that forms the matrix which holds the pigment in place". The solvent "or thinner" has been used to reduce the viscosity of the paint for better application & using water "instead of volatile organic compounds which are harmful to the atmosphere" results in getting water-borne paints.
When VOC is used, the binder-solvent combination is known as "the vehicle" & it will be a solution but when the binder is placed in water, it will form dispersion of microscopically small particles (water-borne emulsion paints). Famous polymers used in these paint are homo-polymers or co-polymers of vinyl acetate & acrylic esters.
There is no "universal template" polymer structure, but a basic requirement is that the polymer should be capable of chemically interacting with water by hydrogen bonding. Ex: NIPAM, PVA, PEG, PEI etc...
Dear Maziar, I answered your question & I was also notified by e-mail that Dr. Sridhar Vadahanambi answered it but the 2 answers do not appear. I wonder why?!
