Kinetics of copolymerization reactions of diallyldimethylammonium chloride (DADMAC) and dimethyl acrylamide (DMA) in aqueous solvent is studied, with highlights on features that control many aspects of the polymeric materials behavior throughout and post‐synthesis. The aim of this study is twofold; first, to offer a method to study the impact of the incorporation of the cationic DADMAC on the composition drift, molecular mass of the copolyelectrolyte, and on the polyelectrolyte behavior by monitoring in real time the copolymerization reactions with a neutral monomer under different conditions. Additionally, it is meant to make the transition toward the next step, controlling the reaction kinetics during designed semi‐batch experiments designed to achieve the average mass and composition distributions desired.

Nonwoven organic–inorganic fiber mats of poly(methyl methacrylate)‐graft‐poly(dimethyl siloxane) copolymers with various PDMS contents were produced by the electrospinning process. The average fiber diameter increased from 0.7 to 3 μm with increasing PDMS content. The fiber mats were used in the preparation of silicone‐laminated composite materials by distributing them (single, double and triple layer mats) in a silicone matrix prior to thermal curing. The composites showed a remarkably good fiber distribution in the silicone matrix. In general the stiffness and strength increased in the presence of fiber, and surprisingly, so did the toughness/extensibility. An interesting feature was that the most silicon‐rich fibers showed clear signs of yielding after tensile testing and failure. This, together with the greater compatibility of the fibers with the matrix because of the higher PDMS content, most probably favored composite toughness. All composite fracture surfaces were characterized by clear signs of fiber pull‐out. Fracture initiation areas were difficult to locate, and this is accredited to an even distribution of the individual fibers in the matrix. POLYM. ENG.
