| titleOfInvention | Carbodiimides quasi-oligomer containing steric hindrance and its preparation method and application |
| abstract | The invention discloses a kind of carbodiimides quasi-oligomer and its preparation method and application containing steric hindrance, the carbodiimides quasi-oligomer containing steric hindrance, raw material of the present invention is cheap, preparation method is simple, therefore lower production costs, it can be widely applied in polyurethane industrial, polyurethane products can be allowed to hydrolyze (condition is 70 DEG C, 95% relative humidity) 80% or more physical property (i.e. tensile break strength) holding afterwards in three weeks as stabilisers against hydrolysis；The present invention solve polycarbodiimide class product in the prior art no matter fusing point height, all abnormal expensive defect of price, easy to promote and utilize, the carbodiimides quasi-oligomer containing steric hindrance is random copolymer shown in formula (V). |
