New Prepolymer compositions derived from liquid methylene bis (phenyl-isocyanate) and polytetramethylene ether glycol |
| abstract |
The present invention is a prepolymer or quasi polymer formed from the reaction of a given amount of a diphenyl methane diisocyanate having at least 5 percent of the 2,4'-isomer and polytetramethylene ether glycols having a molecular weight between 150 and 3000. The glycol which may be combined with other polyether or polyester glycols. The resulting NCO-terminated prepolymer or quasi polymer is a liquid which is stable at temperature of 15°C for at least 24 hours. |
