Sucrose acrylate derivatives can be converted into polymers and hydrogels that can be used as flocculants, water adsorbents, bioimplantables, and dmg dehvery devices (42). Sucrose ethers have appHcations as surfactants and surface coatings, and as feedstocks for synthesis of polyurethane foams and...

Besides the acrylate resins, lactic acid can be converted into other resinous products, which have been covered in the brochure by Long it is clear that synthetic resins, rubber and plasticizers are obtainable from lactic acid and thus ultimately from sucrose. 

More recently, El Modhy et al. investigated the hydrolysis of sucrose over Kappa carrageenan/acrylic acid graft-copolymers (kC-g-AAc) prepared by y-radiation. They showed that the catalytic activity of the kC-g-AAc was dependent on the reaction temperature [29]. As expected, at 80°C, the activity was higher than at 30°C because of lower diffusional resistance.

The term polyacrylates includes synthetic, high molecular weight polymers of acrylic acid (polyacrylic acid or PAA) that are also known as carbomers. They are either linear or (weakly) cross-linked (either by allyl sucrose (carbomers) or by divinyl glycol (polycarbophils)) polymers that are broadly applied in... 

Figure 4.2 Sucrose containing biodegradable polymers. I -O-vinyl hexanedioyl-sucrose co-polymerized with either acrylic acid or acrylamide [21].

This acceleration has been explained by the hydrogen-bonding interaction of the copolymer with the substrate. Poly(p-styrenesulfonic acid-co-acrylic acid) has been found to catalyze the hydrolysis of amylose and sucrose Partially o-benzyl-... 

Carbomer polymers are formed from repeating units of acrylic acid. The monomer unit is shown above. The polymer chains are crosslinked with allyl sucrose or allyl pentaerythritol. See also Section 4. 

Carbomers are synthetic, high-molecular-weight, crosslinked polymers of acrylic acid. These poly(acrylic acid) polymers are crosslinked with allyl sucrose or allyl pentaerythritol. The polymerization solvent used most commonly was benzene however, some of the newer commercially available grades of carbomer are manufactured using either ethyl acetate or a cyclohexane-ethyl acetate cosolvent mixture. The Carbopol ETD resins are produced in the cosolvent mixture with a proprietary polymerization aid, and these resins are crosslinked with a polyalkenyl polyether. 

L-lactic acid has long been used as a food additive and has recently received great attention because it can be used as an important feedstock for the production of other chemicals such as polylactic acid (PLA), acetaldehyde, polypropylene glycol, acrylic acid, and penta-dione. Among them, PLA is the most important product as it can be used to manufacture thermo-formed containers, packaging, nonwovens, paper-coated articles, and film products. Lactic acid can be produced from sucrose, whey (lactose), and maltose or dextrose from hydrolyzed starch using Lactobacillus strains. 

Researchers, primarily from Moscow State University, Russia, have also formed noncovalent aggregates between enzymes and polymers [palmitoylated poly (sucrose acrylate)], polyelectrolytes (polybrene), and block copolymers. Reported enzymatic activities were high. For the former, activity decreased as the molecular weight and degree of palmitoylation increased. Chymotrypsin-polyelectrolyte and -block copolymer complexes were active in aqueous-polar organic co-solvent mixtures when the ionic strength was increased. " ...
