| titleOfInvention | A kind of solid-state semicrystalline unsaturated polyurethanes prepolymer and preparation method thereof |
| abstract | The invention discloses a kind of solid-state semicrystalline unsaturated polyurethanes prepolymers and preparation method thereof, 50 DEG C 145 DEG C of the melting range of the polyurethane prepolymer, melt viscosity≤100mpa.s, range of number-average molecular weight is between 250 to 5000, degree of unsaturation is 0.3 6mmol/g, react being made by NCO/OH equivalent proportions 0.8 to 1.2 for reactive material for ether capped dose with unsaturated alcohol with alkane chain base dihydric alcohol, polyisocyanates.The prepolymer is the solid polyurethane prepolymer with 50 DEG C of 145 DEG C of melting ranges for meeting construction property requirement, it not only shows good stability during storage, also there is sufficiently low melt viscosity prepolymer and the resin Composition containing the prepolymer to be made to apply and obtain excellent levelability in substrate surface, the degree of unsaturation of effective compensation resin system in light heat solidification process. |
