Phosphazene azide coupling agents and their use in rheology modification of polymers |
摘要 |
The present invention relates to cyclic phosphazene azides and their use in a process for producing a rheology modified polymer which comprises contacting a polymer with a cyclic phosphazene azide at a temperature which is at least the decomposition temperature of the cyclic phosphazene azide. When the cyclic phosphazene azide reacts with the polymer, at least two separate polymer chains are advantageously joined and the molecular weight of the polymer chain is increased.
