Process for durably modifying a shaped synthetic polymer article

摘要

A shaped synthetic polymer article having an enhanced desired function is prepared by preparing a shaped synthetic polymer article in which at least the peripheral surface portion of said article contains 0. 1% or more, based on the weight of said shaped article, of a compound (A) having, per molecule thereof, at least one unsaturated radical of the formula (I): ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 respectively denote, independently from each other, a hydrogen atom or an organic radical, and; by copolymerizing the compound (A) contained in the shaped article, with at least one compound (B) which has, per molecule thereof, at least one unsaturated radical of the above-mentioned formula (I) and at least one other functional radical capable of imparting a desired function to the shaped article.
