Abstract

Soy-protein polymer (SPP) can be blended with bioabsorbable polyphosphate fillers to form water-resistant biocomposites for beneficial uses in moist environments where unfilled SPP in unusable. How th adhesion promotor or coupling agent is applied dets. the water resistance or time-controlled hydrolysis of the polymer.
