PROCESS FOR MODIFYING THE SURFACE PROPERTIES OF RESIN PRODUCTS BASED ON VINYL CHLORIDE USING LOW TEMPERATURE PLASMA

摘要

P THE INVENTION RELATES TO A PROCESS FOR MODIFYING THE SURFACE PROPERTIES OF A SHAPED PRODUCT MADE FROM A RESIN COMPOSITION BASED ON VINYL CHLORIDE, CHARACTERIZED IN THAT THE SURFACE OF THE PRODUCT IS SUBMITTED TO AN INTERMITTENT EXPOSURE TO A LOW TEMPERATURE PLASMA ATMOSPHERE OF NON-ORGANIC GAS, UNDER PRESSURE BETWEEN 0.001 AND 10 TORR, THE DURATION OF THE TREATMENT CONSISTING OF ALTERNATE EXPOSURE AND REST TIMES. /P
