Abstract
A method for constructing a laminate comprising two layers, including an acrylic homopolymer layer and a microporous PTFE layer wherein the acrylic layer is a felt and is pretreated by immersion into an adhesive solution and introduced to the PTFE layer and subjected to heat and pressure to form a laminate useful as a filtration material. A laminate useful as a filtration material is formed by the immersion process.
