Impregnation of polystyrene with trichlorofluoromethane |
| abstract |
A PROCESS HAS BEEN DEVELOPED FOR IMPREGNATING POLYSTYRENE PARTICLES WITH TRICHLOROFLUOROMETHANE (FREON 11) USING SELECTED NON-IONIC SURFACTANTS DISPERSED IN THE BLOWING AGENT RATHER THAN IN THE WATER PHASE AS IS CUSTOMARY. SUITABLE SURFCTANTS ARE, FOR EXAMPLE, POLYOXYETHYLENE (20) SORBITAN MONOLAURATE, POLYOXYETHYLENE (23) LAURYL ETHER, POLYOXYETHYLENE (20) MONOLAURATE, POLYOXYETHYLENE (20) NONYLPHENOL, AND MIXTURES OF THESE WITH AN EQUAL AMOUNT OF DI-TERTIARY ACETYLENIC GLYCOL. |
