Abstract: Provided are pre-dynamically cross-linked compositions including a networking additive including a flame retardant species. Specifically, such compositions include a polymer component including a pre-dynamic cross-linked polymer composition. The pre-dynamic polymer composition includes polyester component chains joined by a coupler component, the coupler component including a flame retardant species. A method of preparing a dynamic cross-linked polymer composition includes: reacting a coupler component including at least two reactive groups and a flame retardant species with a chain component including a polyester. The reacting is performed under such conditions so as to form a pre-dynamic cross-linked composition, and is performed in the presence of at least one catalyst that promotes formation of the pre-dynamic cross-linked composition. The pre-dynamic cross-linked composition, when subjected to a curing process, exhibits certain plateau modulus characteristics and has the capability of relaxing internal residual stresses.

Abstract: The disclosure concerns compositions comprising: from about 40 wt. % to about 99.5 wt. % of a polymer base resin; N from 0 wt. % to about 60 wt. % of a reinforcing filler; from 0 wt. % to about 25 wt. % of a lubricant; and from about 0.05 wt. % to about 6 wt. % of a cross-linking agent; wherein the composition is treated to induce cross-linking, wherein the combined weight percent value of all components does not exceed 100 wt % and wherein the composition shows improved tensile fatigue versus a corresponding composition without the cross-linking agent.
