| titleOfInvention |
Polymers and copolymers prepared by the addition of di-hydroxy or di-amino terminated oligomers to bisoxazinones or bisoxazolines |
| abstract |
Polymers and copolymers containing at least one repeat unit of the formula: <IMAGE> in which: - X is O or NH, - R is a single bond or a hydrocarbon chain, - R' is a hydrocarbon chain containing one or two carbon atoms, - P is the residue of an oligomer HX-P-XH whose solution viscosity, determined in meta-cresol at 30 DEG C and a concentration of 0.5 g/dl is lower than 0.50 dl g<-1>. Process for obtaining these polymers and copolymers. |
