The short-chain acrylic monomers like methyl methacrylate and other monomers like styrene produce harder, more brittle polymers, with high cohesion and strength characteristics. ; The long-chain monomers like butyl acrylate and 2-ethyl hexyl acrylate enable soft, flexible, tacky polymers with lower strength characteristics. Monomers like ethyl acrylate, butyl methacrylate, and vinyl acetate contribute more intermediate glass transition and hardness values. ; Co-monomers such as acrylonitrile and (meth)acrylamide, can improve solvent and oil resistance. http://www.mascotchem.com/monomers-and-polymers/acrylate-monomers/
