Abstract
The present invention relates to a method to produce a polymeric sheet comprising the steps of providing an acid-based polymer, providing a neutralizing agent, the neutralizing agent being 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 oil, mixing said acid-based polymer, said neutralizing agent, said processing oil, to obtain a polymeric composition, and processing said polymeric composition to form a polymeric sheet. The polymeric sheet may be used as a component, or as a substrate, of a surface covering. The polymeric sheet may also be used to form polymeric particles which are component of so-called “homogenous”, or substrate-free, surface covering.
