Claims
- 1. A method for modifying the surface properties of a shaped article of an acrylic resin containing no surface active agent which comprises the steps of
- (a) subjecting the surface of the shaped article to exposure to low temperature plasma of a gas having no polymerizability in the plasma condition,
- (b) bringing the plasma-treated surface of the shaped article into contact with an aqueous liquid containing a surface active agent,
- (c) rinsing the surface of the shaped article with water, and
- (d) drying the surface of the shaped article.
- 2. The method as claimed in claim 1 wherein the gas having no polymerizability in the plasma condition is carbon monoxide or a gaseous mixture containing carbon monoxide.
- 3. The method as claimed in claim 1 wherein the length of time in which the plasma-treated surface of the shaped article is in contact with the aqueous liquid containing a surface active agent is at least 1 second.
- 4. The method as claimed in claim 1 wherein the concentration of the surface active agent in the aqueous liquid is in the range from 0.01 to 10% weight.
