The preparation of graft copolymers—XII

Deposition of polymer complex layers onto nonwoven textiles

“…This method has been successfully used to graft AA on polyesters. 3,4 According to literature data, [1][2][3] thin polymeric layers can be formed on polyamide or polyester fiber surfaces with the use of peroxide groups formed previously by heating in air at 80-1008C, followed by grafting with a monomer within a short time to avoid diffusion inside the fibers. Photochemical grafting with UV light and photoinitiators such as benzophenone and related compounds is also reported.…”

“…Methods of producing grafted copolymers with the use of acrylic or methacrylic acid have been reported. [1][2][3][4][5][6] More recent reports have been concerned with the possibility of depositing several layers onto flat or spherical surfaces using the layer by layer technique. 7 This method consists of the formation of the first layer on a surface by grafting, chemical modification, or a strong adsorption.…”

Deposition of Poly(ethyleneimine)/Poly(2-ethyl-2-oxazoline) Based Comb-Branched Polymers onto Polypropylene Nonwoven Fabric Using the Layer-by-Layer Technique. Selected Properties of the Modified Materials

“…The first layer is commonly formed either by grafting of a polymer onto the surface or by chemical modification. The successful grafting of acrylic acid onto polyester surfaces is a well-established procedure [10][11]. Once grafting is completed, a layer of a polymer containing basic functional groups can be applied leading to formation of a stable polymer complex onto which another oppositely charged layer can be deposited.…”
