“…Waterborne polyester can be stably dispersed in water, the molecular chains were fully stretched to form micelles. Monomers and water‐soluble initiators were swelled into micelles and polymerized by physical adsorption or chemical bonding . Wherein, the hydrophilic end distributed ─COO − on the polyester molecular chains and acrylate monomer, which made the surface of the “latex particles” negatively charged to form an electric double layer structure.…”

Waterborne saturated polyester (WSP) with high hydroxyl content was prepared through solution polymerization by using stepwise feeding and stage heating methods. The stability of polyester dispersion was enhanced in terms of molecular structure and polymerization process. The conditions of polymerization process, monomer types, and catalyst type were determined. The effects of the ratio of alcohol-to-acid, trimethylolpropane (TMP) content and the feeding method, the content of terminal monomer and branched monomer on the dispersion were investigated. The stability of the self-emulsifying polyester and the water resistance of the film were proved to be excellent. Through transesterification, waterborne unsaturated polyester (WUP) was synthesized by WSP. Polyester-acrylate composite emulsion can be obtained by physical blending or chemical copolymerization of synthetic waterborne polyester. The viscosity of the composite emulsion was improved, and the hardness and water resistance were improved.

“…Effect of the ungrafted acrylic polymer (that is, the polymer that did not reacted with polyester) on mechanical properties was discussed. Ungrafted acrylics after neutralization are soluble in water; therefore, they can be removed by ultracentrifuge described in a previous article 13. Results are shown in Table IV.…”

Mechanical properties of grafted polyesters were discussed. In the case of grafting of acrylics of more than 25% in the grafting product, mechanical properties of the grafting products decreased greatly compared with the raw polyester. The influence of the molecular structure of the grafted polyester was not observed. The effect of composition of the grafted polymers was discussed. Mechanical properties varied with the composition of the side chain. In the case of grafting onto aromatic polyesters, grafting of an aromatic unsaturated monomer improved the mechanical properties of the grafted polymer. On the other hand, in the case of grafting onto an aliphatic polyester, grafting of an aliphatic unsaturated monomer improved mechanical properties of the grafting polymer. We found that the grafting of the polymer having a high compatibility with the polyester improved the mechanical properties of the grafting products, from the determination of the compatibility of each polymer and the mechanical properties of the grafting products.

Structural study of two grafted polyesters, which were different in mechanical properties, was investigated by DMA, TEM, and high‐resolution solid‐state 13C‐NMR. Using DMA and TEM, a separated phase larger than 100 nm was not found in the grafted polyesters. The main chain and the side chain seemed miscible. Analysis of T1ρHs and their distributions made the difference of microstructure in the grafted polyesters clear. P(EA‐AA)‐grafted polyester, which was very brittle, had a separated phase in the grafted polyester. The separated phase was estimated to be at a size of about 3 nm. On the other hand, P(St‐DEF‐MAnh)‐grafted polyester, which was very ductile, had a homogeneous microstructure. The difference in the microstructures of the grafted polyesters seemed to effect the mechanical properties of the grafted polyesters. © 2000 John Wiley & Sons, Inc.
