Abstract
Compositions comprising a non-isocyanate based thermoplastic polymer and a finely divided isocyanate based thermoset polymer are disclosed. The compositions can optionally further comprise an adhesive thermoplastic compatibilizing agent. Finely divided scrap isocyanate based thermoset polymer materials can be used in preparing these compositions, thus lowering manufacturing and disposal costs. A method to prepare these compositions is also disclosed.
