SURFACE TREATMENT OF POLYMER ARTICLE

PURPOSE:To improve uniformity in the dyeing of a polymer article and in surface hardness thereof, by irradiating a polymer article composed mainly of diethylene glycol bisallyl carbonate with light having a specified wavelength in an O2-free atmosphere. CONSTITUTION:Not less than 50mol% of diethylen...

Beschreibung
Zusammenfassung:	PURPOSE:To improve uniformity in the dyeing of a polymer article and in surface hardness thereof, by irradiating a polymer article composed mainly of diethylene glycol bisallyl carbonate with light having a specified wavelength in an O2-free atmosphere. CONSTITUTION:Not less than 50mol% of diethylene glycol bisallyl carbonate and not more than 50mol% of other copolymerizable monomer such as styrene are cast-polymerized in the presence of a free radical generating polymn. initiator to produce a polymer article which is then irradiated with light having a wavelength of 500mmu or below for 5min-20hr in an atmosphere having an oxygen partial pressure of 100mm.Hg or lower. EFFECT:The polymer article has excellent wear resistance and can be uniformly dyed by using a disperse dye. USE:Sunglass lens, optical filter, etc.
