摘要： An embodiment relates to a polymeric composition for a polythiourethane-based optical material, wherein the polymeric composition, comprising a particular additive, may appropriately adjust the reactivity of an isocyanate such that viscosity is maintained low for a predetermined period of time, and thus is capable of preparing a high-quality polythiourethane-based optical material, without a complicated purification process. Moreover, a polythiourethane-based optical material according to an embodiment has not only a uniform refractive index, but also a low yellow index, and thus may be used as a variety of plastic optical lenses, such as an eyeglass lens or a camera lens and the like.

摘要： The present invention provides a cross-linking non-fluoro hydrophobic aqueous polyurethane dispersion, which is produced by selecting a compound comprising alcohols, amines, acids, saturated or unsaturated (double-bonded or epoxidized) aliphatic long chain carbon-carbon groups or polydimethylsiloxane comprising alcohol groups, amines, oxosilane to be reacted with IPDI to obtain a PU prepolymer; adding a compound having tertiary amines to neutralize the carboxylic acid of PU prepolymer and adding water to disperse the PU prepolymer; and adding a ambient temperature cross-linking agent to obtain a cross-linking hydrophobic aqueous PU dispersion of the present invention. The hydrophobic aqueous-based PU resin has no fluorine which is friendly to the environment, and may further self cross-links on its applications on fabric, paper, wood, glass and metal surfaces, respectively on drying at ambient temperature which is energy saving process. Its cross-linking reaction of this hydrophobic PU system that will achieve a long-lasting water repellent surface treatment.
