Estimating the term…
A method for the preparation of a polyamide-based composition provides for the substantially uniform dispersion of particulate silica and, optionally, mineral oil and any other lubricant additive, within a polyamide matrix. The method includes mixing particulate silica, and optionally, mineral oil and other lubricant additives, to one or more polyamide-producing monomers, and water, to form an emulsion or suspension wherein the particulate silica (and mineral oil and other lubricant additives, when added) are substantially uniformly dispersed therein, and then in situ polymerizing the monomer(s) to provide a polyamide matrix wherein the particulate silica, and optional mineral oil and other optional lubricant additives, remain substantially uniformly dispersed in the resulting polyamide matrix to form the polyamide-based composition. A polyamide-based composition comprising a polyamide matrix having silica and optionally, mineral oil and other lubricant additives, substantially uniformly dispersed within the polyamide matrix is also provided.
A method for the preparation of a polyamide-based composition comprising particulate silica substantially uniformly dispersed into a polyamide matrix, the method comprising:
A method for the preparation of an polyamide-based composition comprising particulate silica and mineral oil substantially uniformly dispersed into a polyamide matrix, the method comprising:
A polyamide-based composition comprising a polyamide matrix having silica substantially uniformly dispersed within the polyamide matrix and wherein mineral oil is substantially uniformly dispersed within the polyamide matrix with the silica.
