tert-Butyl Methacrylate Low Stabilizer (TBMA LS) is an ester of Methacrylic acid and is used as a raw material component in the synthesis of polymers. The ester is a monofunctional monomer with a characteristic high reactivity of methacrylates and a bulky hydrophobic moiety. It forms homopolymers and copolymers which can be obtained from acrylic acid and its salts, amides, and esters, etc.
tert-Butyl Methacrylate Low Stabilizer (TBMA LS) is a very useful starting material for chemical syntheses because it readily undergoes addition reactions with a wide variety of organic and inorganic compounds.
Features & Benefits:
tert-Butyl Methacrylate Low Stabilizer can be used in emulsion polymerization similar to other well-known acrylates like Butyl Methacrylate or Methylmethacrylate. As the hydrolytic stability under harsh acidic conditions is reduced for tert-Butyl Acrylate (elimination of iso-butylene), it is recommended to use for the polymerization a pH range of 3-4 (controlled via puffer or alkaline substances like ammonia or bicarbonate). With a higher share of TBMA (as a substitute of MMA) in the polymer, we observe an increased tendency of cross-linking. Most probably due to the higher backbone crosslinking tendency of acrylates compared to methacrylates(radical transfer to polymer chain/backbone). Best results concerning particle size distribution were achieved by using a polymer seed, either as a ready polymer dispersion (e.g. polystyrene) or as an in-situ polymer seed.
