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.
