실험 절차

HEMA monomer (with an impurity level lower than 0.8% purchased from Rohm) was mixed with triethylamine (≧99.5% pure, from Fluka) and petrol ether (bp 40-60° C.) passed through aluminum oxide and reacted with trimethyl chlorosilane (≧99.0% pure, from Fluka) to obtain trimethylsilyloxyethyl-methacrylate (TMS-HEMA). TMS-HEMA was purified by distillation from calciumhydride (once) and triethylaluminum (electronic grade, from Aldrich) (twice).
