Method to produce a surface covering

A method to produce a polymeric surface covering, said method comprising the steps of:

• providing an acid-based polymer;
• providing a neutralizing agent selected from the group consisting of an organic metallic compound, a metallic salt of a fatty acid, and an ionomer, or a mixture thereof;
• providing a processing additive;
• mixing said acid-based polymer, said neutralizing agent and said processing additive, to obtain a polymeric composition;
• processing said polymeric composition to form a polymeric sheet;
• providing a backing sheet;
• applying said polymeric sheet and said backing sheet to form a multiple layer surface covering.
