Duan, Wangwang; Li, Xiaorui; Shen, Yiding; Yang, Kai; Zhang, Hua published the artcile< Synthesis of highly branched water-soluble polyester and its surface sizing agent strengthening mechanism>, Product Details of C19H34O2, the main research area is water soluble polyester surface sizing agent strengthening mechanism synthesis.

Solvent-free and highly branched watersol. polyester (WPET) is prepared through self-emulsification methodol., using di-Me terephthalate (DMT), sodium di-Me isophthalate-5-sulfonate (SIPM), trimethylolpropane (TMP), and ethylene glycol (EG) by the transesterification and polycondensation. The WPET were first utilized as surface-sizing agents for cellulose fiber paper. The structure, average mol. weights, and phys. properties of the water-soluble polyester were characterized by FTIR, 1H NMR, gel permeation chromatog. (GPC), dynamic light scattering (DLS), X-ray diffraction (XRD), and dynamic rheometer. The effects of polymer structure and properties, as well as the surface sizing of the paper, were investigated. WPET displayed better surface sizing properties when it was prepared under the following conditions: -COO/-OH molar ratio of 1:2, the SIPM content of 17.98%, and TMP content of 11.10%. The relationships between the WPET structure and sized paper were clearly illustrated. The mech. properties and water resistance of sized paper did not only depend on multi-branched hydroxyl groups of the WPET chains but also relied on the interactions among polymers and fibers, as well as the high toughness of surface sizing agent. The sizing paper possesses excellent mech. properties as well as water resistance.
