Method and compositions for producing polymer blends

摘要

Methods for mixing nylon compounds and compositions useful in mixing nylon compounds are provided. The methods and compositions disclosed are useful in producing nylon for wire and cable jacketing. The disclosed methods provide nylon having a reduced heat history compared to traditional methods. The disclosed methods and composition provide additional mixing capacity by reducing the amount of nylon that must be incorporated with additives per unit of final nylon composition. The disclosed methods and compositions provide the ability to select from a plurality of additive concentration levels in the final product by varying the ratio of a masterbatch compound containing a high concentration of the additive to a resin containing a low concentration or no additive.

主权项

1. A method of producing a mixture having a predetermined concentration of an additive and a predetermined concentration of caprolactam comprising the steps of:
providing a first polymer compound, the first polymer compound comprising a polymer resin, a first concentration of the additive, wherein the first concentration of the additive is from 0 wt. % to the predetermined concentration of the additive, and a first concentration of caprolactam, wherein the first concentration of caprolactam is from 0 wt. % to the predetermined concentration of caprolactam; providing a second polymer compound, the second polymer compound comprising the polymer resin, a second concentration of the additive, wherein the second concentration is greater than the predetermined concentration of the additive, and a second concentration of caprolactam, wherein the second concentration of caprolactam is greater than the predetermined concentration of caprolactam, wherein the first polymer compound polymer resin is identical to the second polymer compound polymer resin; and combining the first and second polymer compounds to achieve a mixture having the predetermined concentration of the additive and the predetermined concentration of caprolactam.
