Synthesis of PPG-TDI-BDO polyurethane and the influence of hard segment content on its structure and...

Polyurethane have good anti-protein adsorption properties, could be used as an antifouling material. In this study, a type of polyurethane antifouling coating was prepared using 2,4-toluene diisocyanate and 1,4-butanediol as the hard segment and polyether polyols as the soft segment. The influence of hard segment content on the chemical structure,...

Performance of palm oil‐based dihydroxystearic acid as ionizable molecule in waterborne...

Waterborne polyurethane dispersions (WPUDs) containing a renewable palm oil-based 9,10-dihydroxystearic acid (DHSA) as an isocyanate-reactive compound bearing ionizable carboxylic group to incorporate hydrophilic groups into the polymer chain have been successfully prepared. The WPUDs were prepared by using polyether and polyester polyols of 2000...

Polyisobutylene (PIB)-based polyurethanes (PUs) exhibit unparalleled hydrolytic-oxidative-biologic stability and are melt processible, however, their mechanical (strength) properties are modest mainly due to insufficient H bonds. We posited and demonstrate that the ultimate properties of PIB-PUs are enhanced, while their melt processibility is...

CHEMISTRY
Preparation and Characterization of a Polymer-Based Molecular Accordion

A urethane-based polymer material, denoted HDI-1, was obtained from the addition reaction of β-cyclodextrin (β-CD) with 1,6-hexamethylene diisocyanate (HDI) at the 1:1 mole ratio. In aqueous solution and ambient temperature conditions, HDI-1 adopts a compact (coiled) morphology where the cross-linker units become coiled and are partially...

Non-Isocyanate Polyurethanes from Carbonated Soybean Oil Using Monomeric or Oligomeric Diamines To...

Fully bio- and CO2-sourced non-isocyanate polyurethanes (NIPUs) were synthesized by reaction of carbonated soybean oil (CSBO) either with biobased short diamines or amino-telechelic oligoamides derived from fatty acids to achieve respectively thermoset or thermoplastic NIPUs. Biobased carbonated vegetable oils were first obtained by metal-free...
