Title: Method for preventing non-rigid vinyl chloride resin film or sheet from being hardened
Inventor: MIYOSHI MOTOYUKI
IPC: C08J7/00
Filed: 1982-10-28
Abstract: PURPOSE:To prevent a non-rigid vinyl chloride resin film or sheet from being hardened even when laid under the ground or water over a long period of time, by subjecting the region (to be laid under the ground or water) of said vinyl chloride resin film or sheet and its vicinities to a phasma treatment. CONSTITUTION:The region (to be laid under the ground or water) of a film or sheet of a non-rigid vinyl chloride resin (e.g. obtd. by blending 20-80pts.wt. plasticizer with 100pts.wt. vinyl chloride resin) and its vicinities are subjected to a plasma treatment. By this treatment, the plasticizer is prevented from oozing out of the film or sheet and hence the film or sheet is hardly hardened. Since this treatment is applied only to the region to be laid under the ground or water and its vicinities, the cost for the plasma treatment is reduced and there can be minimized such attendant disadvantages that the film or sheet becomes yellowish, or feels hard by the plasma treatment.
