Abstract: Disclosed herein are thermoplastic compositions comprising: from about 0.01 wt. % to about 90 wt. % of a polyalkylene terephthalate, wherein the polyalkylene terephthalate component comprises at least a first and a second polyalkylene terephthalate polymer, wherein the first polyalkylene terephthalate has a molecular weight of from about 80,000 g/mol to about 300,000 g/mol as measured by gel permeation chromatography with polystyrene standards; from about greater than 0 wt. % to about 50 wt. % of a glass fiber; and from about 0.01 wt. % to about 45 wt. % of a high heat polymer, wherein the combined weight percent value of all components does not exceed 100 wt. %, and all weight percent values are based on the total weight of the composition.

Abstract: In the process of the invention, a composition is made by mixing a plurality of microcapsules containing at least an additive such as lubricants, oils, fragrances, colorants, etc., with a dispersing polymeric material to form a first blend, and compounding the first blend into a base containing at least a polymeric material at a temperature of less than 370° C., whereas the resulting composition is substantially free of segregated microcapsules and heat degraded shell.
