  • High modulus polyurea elastomers prepared with amine-initiated polyols
    Patent number: 4595743
    Abstract: A polyurea or polyurea-polyurethane elastomer which is the reaction product of reaction mixture comprising (a) an organic polyisocyanate, (b) a low equivalent weight aromatic amine chain extender in an amount from about 15 to 60 parts by weight based on the weight of isocyanate reactive components present in said reaction mixture, (c) an amount of an amine-initiated polyol sufficient to provide the elastomer with a measurably decreased brittleness at demold as compared to a similar elastomer prepared in the absence of said amine initiated polyol.
