Abstract From the Canadian patent

Synthetic sheet material is resistant to decay by fungus and other microbial organisms and particularly useful in shoe construction where flexibility is required. The material comprises a uniform distribution of cellulose and optionally synthetic fiber within an acrylic elastomeric matrix or binder and is formed from a furnish of the fibers; a metallic quinolinolate which lends the material decay resistant; a polymer colloid such as an acrylic latex which prevents the coagulation of the subsequently added acrylic elastomeric binder by the metallic quinolinolate; and a cationic polymer which acts a a retaining agent for the metallic quinolinolate in the synthetic sheet material.
