| titleOfInvention | MDI-based isocyanate-terminated prepolymers and polyurethane foams prepared therefrom |
| abstract | The present invention relates to an MDI-based isocyanate-terminated prepolymer and a hydrophilic polyurethane foam produced therefrom. In a first step, forming a polyol mixture at least with a compound comprising a small amount of polycaprolactone triol and one or both selected from glycerol monostearate and glycerol monolaurate based on an equivalent ratio of OH/NCO, and forming a hydroxyl terminated intermediate with TDI; and then, in a second step of reacting MDI with the intermediate formed in the first step, an isocyanate group-ended prepolymer is produced, MDI being 20.0 to 60.0% by weight based on the total weight of the reaction raw materials. The isocyanate group-ended prepolymer based on MDI and the aqueous phase are used for preparing the hydrophilic polyurethane foam plastic, so that the hydrophilic polyurethane foam plastic has better processing and reaction characteristics and excellent physical properties. |
