MMA (commercial grade, Siam Chemical Industry, Samutprakarn, Thailand) and DVB stabilized with 0.2% 4-tert-butylpyrocatechol (65% DVB isomers and 33% ethyl vinylbenzene measured by GC, technical grade, Merck, Darmstadt, Germany) were each washed with 10% aqueous sodium hydroxide solution (BDH, Poole, Dorset, U.K.) and then by water, dried over anhydrous sodium sulfate (Carlo Erba, Milan, Italy), and passed through the activated form of aluminum oxide (100-125 mesh) column (Fluka, Buchs, Switzerland) to remove the residual inhibitors.
Polystyrene is a thermoplastic formed by addition polymerization of the monomer vinylbenzene, a.k.a, styrene, [C.sub.6][H.sub.5]CH = C[H.sub.2].
Styrene, a colorless, toxic liquid used in making plastics and rubbers, is also known as phenylethylene or vinylbenzene. The institute's study is the first to confirm through lab tests the possible danger of styrene foam, a commonly used material whose residual effects have thus far escaped close examination.
