실험 절차

Pentadecyl acrylate was prepared by esterification of acrylic acid with 1-pentadecanol under standard conditions. Crude monomer was recrystallized from three volumes of ethanol and dried in vacuo. Ten grams of pentadecyl acrylate was dissolved in 20 ml of oxygen free ethylacetate containing 0.10 grams of azobis-isobutylnitrile (hereinafter AIBN) and stirred in a sealed bottle maintained at 60° C. for 24 hours. The resulting polymer was isolated by precipitation into cold ethanol and dried in vacuo. Analysis of the polymer showed it to have a first order transition temperature of 29° C., a heat of fusion of 59 J/g and a molecular weight of about 175,000 in an uncured state.
