The Interaction of Vinyl Monomers and Poly(ethylene terephthalate) in the Presence of Various Initiators Produces a Physical Mixture, not a Graft Copolymer
Journal of Polymer Science: Part A, Polymer Chemistry
The interaction between poly(ethylene terephthalate) and four vinyl monomers, methacrylic acid, methyl methacrylate, styrene, and vinyl acetate, has been studied using hydrogen peroxide, benzoyl peroxide, azobisisobutyronitrile, and cobalt acetylacetonate as initiators. The ease of addition of the monomer to the polymer follows the solubility of the monomer in the polymer film. No chemical interaction occurs between the PET film and the monomer; rather, the monomer is homopolymerized within the film and forms a semi‐interpenetrating network so that the two homopolymers cannot be separated unless the PET matrix is destroyed.
