Claims14
A collection of glass fibers bound by a polymeric composition, comprising:
- a nitrogenous polymer produced from bulk polymerization of a reactant mixture which includes a reducing-sugar carbohydrate, ammonia and a monomeric polycarboxylic acid, wherein the bulk polymerization of the reactant mixture occurs while the reactant mixture is in contact with the glass fibers and the polymer includes melanoidin products cross-linked with ester linkages between the monomeric polycarboxylic acid and one or more molecules of the melanoidin products.
A collection of glass fibers bound by a polymeric composition, comprising:
- a nitrogeneous polymer produced from a mixture including a reducing-sugar carbohydrate and an ammonium salt of a polycarboxylic acid, wherein the nitrogeneous polymer includes melanoidin products cross-linked with the polycarboxylic acid.
