Copolymers containing various amounts of acryloyl chloride were made with ethyl methacrylate, methyl acrylate, and styrene by bulk polymerization and by conversion of acrylic acid copolymers. Fibers and films of these polymers were crosslinked with ethylenediamine, and it was shown that increased crosslinking led to increased tenscity (at elevated temperature), modulus, zero strength temperature, and thermal stability and also greatly decreased elongation and shrinkage. The average molecular weight between crosslinks was calculated. The effect of crosslinking amorphous fibers and films was shown experimentally to produce materials with properties predicted for more rigid polymer structures.
