摘要： A process for producing shaped articles having improved surfaces, characterized by subjecting a shaped article of a polymer derived from a monomeric material comprising an acrylate and/or methacrylate to at least one of a hot water treatment, an aqueous alkali solution treatment and an aqueous acid solution treatment. Shaped articles obtained by this process have an advantage that when the surfaces thereof are stained the removal of the stains is quite easy. Moreover, they are hydrophilic and have excellent wettability by water. Therefore, said shaped articles are extremely suitable for use as contact lens.

摘要： A laddery lower alkylpolysilsesquioxane represented by the formula: ##STR1## wherein R and R' represent same or different lower alkyl groups, and n represents an average degree of polymerization, said laddery lower alkylpolysilsesquioxane having a heat-resistant thin film-formability, characterized in that 15 to 30% by weight of the lower alkylpolysilsesquioxane is occupied by the portion having a standard polystyrene-reduced molecular weight of 20,000 or less as measured by gel permeation chromatography. Said silicone resin in which R and R' are methyl is prepared by dissolving CH.sub.3 SiCl.sub.3 in a ketone or an ether, adding water to this solution with stirring to hydrolyze CH.sub.3 SiCl.sub.3, condensing the hydrolyzate and, if necessary, subjecting the resulting condensate to a treatment for adjusting the proportion of the low molecular weight portion in the product.
