Novel amphoteric polyurethane dispersions with postpolymerization crosslinking function derived from hydroxylated tung oil: synthesis and properties†
Abstract
Novel hydroxylated tung oil-based amphoteric polyurethane polymer dispersions (HTO-AmPUDs) with postpolymerization crosslinking capability were synthesized and found to be reversibly stable in both acidic and basic media. Reactive HTO-AmPUDs showing surface activity and film properties adjustable with crosslinking are potentially new polymeric components and surfactants in polymer alloy synthesis.
