| مستخلص: |
The article focuses on PolyUrethane Dispersions (PUD). Polyurethane is a polymer that contains a repetitive moiety resulting from the reaction between an isocyanate group and a hydroxyl group. All isocyanates are used for the synthesis of PUD, in which the reactivity of aromatic isocyanates must be higher than that exhibited by the aliphatic isocyanates during the early stage of water dispersion. PUD involves the preparation of high-molecular-weight polyutheranes in a process of controlling viscosity. |
