Process for cellular polymeric products |
| abstract |
ABSTRACT PROCESS FOR CELLULAR POLYMERIC PRODUCTS The invention provides a process for the preparation of a cellular polymeric product which comprises reaction of a polyisocyanate composition with an isocyanate-reactive composition having a functionality of at least 2, in the presence of a blowing agent and in the presence of an inert, organic liquid which is substantially insoluble in the reaction mixture and which is present as the disperse phase of an emulsion or a microemulsion, characterised in that the polyisocyanate composition comprises polymethylene polyphenylene polyisocyanate having a functionality of at least 2.5 and a urethane-modified, isocyanate-ended prepolymer, wherein the isocyanate functionality of the polyisocyanate composition is at least 2.3 and wherein the concentration of urethane linkages in the polyisocyanate composition is in the range from 1 millimole to 150 millimoles per 100 grams thereof. The invention also provides a novel polyisocyanate composition for use in the process and cellular polymeric products prepared according to the process. |
