Method For Producing Polydienes And Polydiene Copolymers With Reduced Cold Flow |
摘要 |
A method for preparing a coupled polymer, the method comprising the steps of: (i) polymerizing monomer to form a reactive polymer; (ii) reacting the reactive polymer with a polyisocyanate having a functionality of X to form an intermediate polymer product; and (iii) reacting the intermediate polymer product with a polyol having a functionality of Y to form the coupled polymer product, where X+Y≧5. |
