The maleic anhydride market in Russia is analyzed. An assessment made of the existing production technologies and optimal technology proposed. scheme with a fixed catalyst bed selected. Possible problems arising at all construction stages are identified ways solving them

Poly(lactic acid) (PLA) and starch copolymers are obtained by reactive blending varying the starch compositions from 0 to 60%. PLA is functionalized with maleic anhydride (MA), obtaining PLA-g-MA copolymers using dicumyl peroxide as an initiator of grafting in order to improve the compatibility and interfacial adhesion between the constituents. PLAþ starch blends without a compatibilizer do not...

Hydrogels are commonly used as scaffolds for the preparation of three-dimensional tissue constructs and encapsulation delivery cells in regenerative medicine. Polyesters an attractive class polymers hydrogel preparation. However, most polyesters have hydrophobic backbones lack pendent groups that can be chemically functionalized. We describe here development water-soluble based on aspartic acid...

Allyl propionate-maleic anhydride-styren terpolymer has been modified with glycerin in order to prepare a new cross-linked functional polymer sorbent. The synthesized cross-linked polymer sorbent has a network structure and contains carboxylic acid, carbonyl, hydroxy, and ester groups, all of which are capable of interacting with metal ions. The sorption behavior of UO 2 ions under optimum sorp...
