Compositions and flooring materials using them |
(57) A flooring felt composition comprises a fibre material such as cellulose or wood
fibers, a synthetic rubber latex binder, fillers, and antioxidants. The binder is
a latex copolymer made from a vinyl substituted aromatic monomer, a conjugated diene
monomer, an unsaturated acid monomer, and a functional cross-linking agent other than
said acid monomer. The flooring felt is useful as a backing for linoleum, floor tile,
and the like. Heat resistance of the felt is improved by excluding acrylic and methacrylic
acids from the unsaturated acid monomer.
