  • Publication number: 20050075446
    Abstract: A process is provided for the production of a very low melt viscosity (high melt flow index) polymer resin, suitable for use in spunbond or meltblown processing. According to the process of the current invention, a high melt viscosity (low melt flow index) resin is subjected to post-reactor molecular weight alteration by extrusion with a chemical prodegradant. The process produces a very low melt viscosity resin that can be used in spunbond or meltblown processing without further treatment to reduce the average molecular weight of the resin. Further, the very low melt viscosity resins produced according to the process of the current invention contain very little or no residual prodegradant.
