摘要：

Two biodegradable polymer intermediates, triacrylate 4 and tetraacrylate 7, were prepared by polycondensation reaction of ethyl beta-hydroxybutyrate using glycerol and pentaerythritol as initiators and dibutyltin oxide as a catalyst, followed by functionalization of the hydroxyl end groups with acryloyl chloride in the presence of triethyl amine. These polymer intermediates were characterized using H-1-NMR and IR spectroscopic analysis and were employed as crosslinking agents during polymerization of partially neutralized acrylic acid to obtain the corresponding potentially biodegradable polyacrylates.
