Waterborne polyurethanes (WPUs) were synthesized by self-emulsification. The WPU was copolymerized with methyl methacrylate (MMA) by emulsion polymerization.The micelle diameters of WPUs and the copolymers were measured by dynamic light scattering method
and the particle morphology was determined by TEM.The results showed that the micelle diameter greatly depended on the component of diol in the WPU’s main-chain
and the micelle diameter composing hydrophilic diol was bigger than that composing hydrophobic diol.With the increase of the flexibility of the side-chain and the rigidity of the main-chain in WPUs
the WPU particles exhibited a shell-core structure.
