Synthesis and Structure of Tetraphenylantimony Methacrylate and Tetraphenylantimony Crotonate and Their Use for the Production of Antimony-Containing Polystyrene

摘要

Tetraphenylantimony methacrylate Ph4SbO2CC(CH3)=CH2 and tetraphenylantimony crotonate Ph4SbO2CCH=CHCH3were synthesized by the action of acids on Ph5Sb or on Ph4SbBr in the presence of Et2NH. According to X-ray diffraction analysis data, both compounds are antimony complexes with distorted tetragonal pyramidal geometry. Polymerization of styrene with Ph4SbO2CC(CH3)=CH2 and Ph4SbO2CCH=CHCH3 additives gave transparent antimony -containing polystyrene soluble in chloroform, dichloromethane, and THF.
