METHOD OF FORMING THERMOPLASTIC FOAMS USING NANO-PARTICLES TO CONTROL CELL MORPHOLOGY

A process for making closed-cell, alkenyl aromatic polymer foams using nano- particle nucleation agents to control the cell morphology of the resulting foam includes forming a polymer melt at a temperature above the polymer glas s transition temperature (for crystal polymers) or the polymer melt poi...
