Process for increasing the melt viscosity and/or melt elasticity of polyamides with aryl phosphoryl azide |
摘要 |
A process for decreasing the melt index and increasing the melt viscosity and melt elasticity of polyamide by adding thereto an effective amount of an aryl phosphoryl azide compound as for example diphenyl phosphoryl azide, and thereafter heating the composition until the desired changes in melt index, melt viscosity and melt elasticity are attained.
