Erythritol polymerization

Thiem et al. [21-23] studied the ring-opening polymerization of 1,4-anhydro-2,3-di-(9-alkyl-D-erythritols (4) using super-acids. [Pg.149]

Funk [3] prepared hydrogels with different pH values by reacting 90 parts of hydrophilic polymeric agents with glacial acrylic acid, water, and penta-erythritol triallyl with 10 parts of acrylic acid, sorbitan monococoate, and allyl methacrylate. [Pg.264]

Erythrose, C4H8O4, is obtained as the result of the oxidation of erythritol, a tetrahydroxy-alcohol. A tetrose can be formed by the polymerization of glycolic aldehyde. The reaction is an example of the aldol condensation (184) —... [Pg.341]

It has also been shown that lipase CA can produce reduced sugar-containing polyesters regioselectively from divinyl sebacate and sorbitol, in which sorbitol was exclusively acylated at the 1 and 6-positions (Scheme 23.11) [115]. Mannitol and meso-erythritol were also regioselectively polymerized with divinyl sebacate. The lipase CA-catalyzed polycondensation of adipic acid and sorbitol also took place in... [Pg.693]
