Method for the preparation of a polyurea resin |
| abstract |
A polyurea resin having excellent mechanical properties along with high heat resistance can be prepared by the reaction of an aromatic polyamine component and an aliphatic polyisocyanate component, in which the aromatic polyamine component is a combination of a first aromatic polyamine compound which is typically a polyoxyalkylene bis(amino-benzoate) compound and a second aromatic polyamine compound selected from various classes of aromatic polyamine compounds different from the first aromatic polyamine compound in a specified weight proportion. The polyurea resin can be imparted with further improved heat resistance when the aliphatic polyisocyanate component is a combination of an aliphatic diisocyanate compound and a cyclic trimer of an aliphatic polyisocyanate compound in a specified weight proportion. |
