A PROCESS FOR PRODUCING THERMALLY STABLE THERMOPLASTIC POLYURETHANES |
摘要 |
A continuous process for the production of thermoplastically processable polyurethane elastomer is disclosed. The process comprise adding acid H compounds in an amount calculated to control and render constant the melt viscosity of the product. The inventive elastomer has constant melt flow behavior and high thermal stability.
