2019年6月4日 — A binary emulsion system via combination of sodium dodecylbenzenesulfonate (SDBS) and polyvinyl pyrrolidone (PVP) was employed to prepare microcapsules containing isophorone diisocyanate. The effect of different concentrations of SDBS and PVP on the size and distribution of capsules was investigated.
The Trimerization of Isocyanate‐Functionalized Prepolymers: An ...
2019年2月28日 — By using in situ infrared spectroscopy, it is shown that the trimerization of isocyanate endgroups is clearly the predominant reaction pathway of network formation, supporting the proposed mechanism and network structure. The resulting networks possess excellent mechanical properties in both the dry and in the wet state.
Isocyanate terminated castor oil-based polyurethane …
2015年3月1日 — In this work, NCO-terminated castor oil-based polyurethane prepolymer (COPUP) is synthesized through the reaction between the isophorone diisocyanate (IPDI) and castor oil (CO) with a variable ratio of the isocyanate (NCO) and hydroxyl (OH) groups (0.5:1; 1:1; 1.5:1; 2:1) analyzed by nuclear magnetic resonance (NMR), Fourier transform infrared ...
One-step thiol-isocyanate dispersion polymerization: Preparation of ...
2016年11月15日 — The thiol-isocyanate particles were prepared by one-step dispersion polymerization. Typical procedure for the preparation was listed as follows. PVP (5.0 g) was dissolved in ethanol (100 g) to form a clear solution, and the solution was introduced to a 250 mL three-necked round
Efficient encapsulation of isocyanates in PCL/PLA biodegradable ...
2023年1月16日 — Microencapsulation of isocyanates eliminates the risks associated with their direct handling, protects the isocyanate species from air moisture, and increases the storage life. In light of this, we present a straightforward and efficient process to encapsulate isophorone diisocyanate (IPDI) using biodegradable polymers by an emulsion system ...
