<p>The present invention is a method to produce composites based on microcapsules or microspheres embedded in continuous polymeric matrices. Both non-bioerodible and erodible polymers can be used. Material can be incorporated into the microcapsules or microspheres for subsequent release. The polymer composites have completely different properties from either a continuous polymer matrix or microcapsules or microspheres and are therefore useful for a wide variety of applications. Figure 1 is a graph of the percent cumulative release of acid orange from microspheres of a polycarboxyphenoxypropane-sebacic acid copolymer.</p> |
