Abstract: This invention relates to a method of modifying a hydrohalogen polymer surface wherein said hydrohalogen polymer is selected from the group consisting of polyvinyl chloride, polyvinylidene chloride, and polyvinyl dichloride which comprises contacting the hydrohalogen polymer surface with an alkali metal alkoxide MOR wherein M is an alkali metal and R is an alkyl group at a temperature of 2* to 106* C for a time increment of 5 minutes to 300 minutes thereby forming an alkoxide-activated surface thereof; contacting said surface with an oxygen-containing oxidizing agent of sufficient strength to convert an olefinic double bond to the corresponding aldehyde or carboxyl group to form an oxygen-activated, alkoxide-activated surface; and electrolessly depositing onto said surface a metal deposit.
