POLYMERIZABLE METHACRYLATE CARBOHYDRATE-DERIVATIVES - 1,2 OPYLIDENE-6-O-METHACRYLOYL-ALPHA-D-GALACTOPYRANOSE AND ROPYLIDENE-3-O-METHACRYLOLY-ALPHA-D-GLUCOFURANOSE/

The title structures, both C16H24O7, have been determined to investiga te the possibility of using these carbohydrate-containing monomers or related compounds for solid-state polymerization. The orientation of t he methacrylate groups in the galactose derivative is suitable for sol id-state reaction but the distance between the potentially reacting vi nyl C atoms is too great, 5.065(5)Angstrom, for a facile reaction. The glucose derivative is disordered, with one of the isopropylidene ring s assuming two different envelope conformations in the crystal. In the glucose derivative there are no approaches of the appropriate vinyl g roup atoms closer than 6439(3)Angstrom.
