| titleOfInvention |
Process for producing solid resilient polymer particles with open pores |
| abstract |
Microscopic particles containing a continuous network of pores open to the particle surface are manufactured by suspension polymerization of an ethylene-propylene-diene elastomeric prepolymer containing a water-immiscible liquid. The particles are useful as controlled-release delivery systems for active substances intended for a wide range of uses including topical applications. The spongy character of the particles enhances their usefulness in applications where high pressure or high temperature are encountered, and where exceptional smoothness of feel is required. |
