Water-borne polyester for inks and coatings: structural elucidation of acrylic-grafted polyester and the particle of its aqueous dispersion

Preparation of an acrylics-grafted polyester and its aqueous dispersion?Structural study of acrylics-grafted polyesters

“…We have previously discussed the molecular structure of the two grafted polyesters 13. These polyesters formed transparent films.…”

“…They consist of “core‐shell” particles with a core of high molecular‐weight polyester. In previous articles, we discussed the preparation and the characterization of an acrylics‐grafted polyester and its dispersion, i.e., the effect of the grafting conditions, reactivities of the grafting monomers, the grafting solvents,10 the grafting methods11 on the molecular structures of the grafted polyesters, the particle structures,13 the particle diameters of their dispersions,10 and the dispersion viscosity and the dispersion rheology 12. We discussed the mechanical properties of the acrylics‐grafted polyesters to make the factor effecting the mechanical properties clear in our previous article 14.…”

Polymer heterogeneity in waterborne coatings

“…80 This will give an ionic group in a hydrolytically insensitive environment and the polyester, which is more prone to hydrolysis, will be positioned in the core of the particle. 81 With their good gloss and nonyellowing characteristics, the main application for polyester acrylic hybrid dispersions has been in inks and coatings.…”

Applications for Automotive Coatings

“…They consist of "core-shell" particles with a core of high molecular weight polyester. Small particle diameters were obtained by use of polyesters having the largest amount of unsaturated bonds unless gelation occurs [24][25][26][27][28][29][30]. Thermosetting water based polyester resin coating composition prepared from polyalkadienediol may be directly applied to wet electrodeposited coating [31].…”
