Gantrez films

The progress of these reactions was followed by various techniques (Table 2). Ellipsometric analysis showed that the increase in film thickness after treating a silicon/Gantrez film with a fourth-generation PAMAM den-... 

Thermal treatment of the nanocomposite film formed in Scheme 6 converts the amic acid groups of the film to imides (Eq. 15). In addition to evidence by IR spectroscopy, elhpsometry showed that the film thickness decreased by ca. 15% and contact angle goniometry showed that the film became more hydrophobic (see Table 2). This thermally treated film also did not have the pH dependent permeability of redox-active ions previously described for dendrimer/Gantrez films on gold substrates [55]. 

In work like that described in Scheme 6, Bruening reported the synthesis of multilayer composites by alternating deposition of Gantrez and the linear polyvalent nucleophile poly(allylamine) [58]. The impermeable films that were produced by this multistep hyperbranched graft chemistry were shown to passivate aluminum surfaces.

Alternating copolymers ( interpolymers ) of maleic anhydride and alkyl vinyl ethers are prepared by free radical polymerization in solvent, non-solvent or bulk media Products prepared from ethyl-, butyl-, hexyl-, and octyl-, and decyl- vinyl ethers are described in Table I. The decyl-copolymer was prepared by Dr A. W. Schultz. A methyl-copolymer ( Gantrez AN General Aniline and Film Corp.), not described in Table I, was included in some studies. Molecular weight estimates were... 

Maleic copolymers, especially those with alkyl vinyl ethers, were used in drug formulations where only physical interactions occurred between the polymer matrix and the therapeutic agent. The polymers used in the formulations should be biocompatible, nontoxic, and should not induce allergic or pyrogenic reactions. Poly(maleic anhydride-co-methyl vinyl ether) (MA-MVE) is such a polymer, being approved by the FDA. Commercialized as Gantrez AN, MA-MVE copolymer is used as pharmaceutical excipient due to its bio/mucoadhesion and excellent film-forming properties [137]. 

Table A.4 shows that Gantrez AN resins and derivatives of these copolymers have been claimed to be useful for controlled-release coatings or binders for and insecticides/ The pharmaceutical film...
