The interaction of the polymer with the filler is promoted by the presence of reactive functionality in the polymer, capable of chemical reaction or hydrogen bonding with the functionality, generally hydroxyl, on the surface of the filler. Thus, carboxyl-containing polymers, e.g. ethylene-acrylic acid copolymers and maleic anhydride- and acrylic acid-grafted polyethylene and polypropylene interact readily with fillers. [Pg.469]

The hyperbranched poly( acrylic acid) graft films -C02H-rich interface on polyethylene can be modified by noncovalent methods just like CO2H-rich interfaces of PAA/Au grafts. This was shown by treating deprotonated 3-PAA/PE films with cationic polyelectrolytes like poly-D-lysine, and amine terminated PAMAM dendrimers at pH 7 [31]. Equation 10 illustrates the entrapment of PAMAM dendrimers in a 3-poly(sodium acrylate)/PE film. In these cases, polyvalent entrapment of the cationic electrolyte was evidenced in the ATR-IR spectriun by the appearance of amide C = O and N - H peaks of the guest dendrimer that were not present in the host 3-poly(sodium acrylate)/PE film.

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. [Pg.67]

Immobilization of glucose oxidase via carbodiimide chemistry onto a poly(acrylic acid) grafted porous cellulose substrate was performed by Ito, et al. (14). They showed that this system s permeability to insulin in response to a 3600 mg% glucose challenge was 1.7 times greater than the permeability prior to the addition of glucose. [Pg.281]
