Foams for woodland and grass fire-fighting have been developed with low drainage (water loss from foam) and high expansion (volume of foam per volume of starting liquid), two parameters traditionally considered to be inversely proportional. The stabilizing additive is poly (methyl vinyl ether/maleic anhydride), thought to cross-react with fatty alcohol components of the foam base via the anhydride function. [Pg.450]

As pointed out by Heller (2), polymer erosion can be controlled by the following three types of mechanisms (1) water-soluble polymers insolubilized by hydrolytically unstable cross-links (2) water-insoluble polymers solubilized by hydrolysis, ionization, or protonation of pendant groups (3) hydrophobic polymers solubilized by backbone cleavage to small water soluble molecules. These mechanisms represent extreme cases the actual erosion may occur by a combination of mechanisms. In addition to poly (lactic acid), poly (glycolic acid), and lactic/glycolic acid copolymers, other commonly used bioerodible/biodegradable polymers include polyorthoesters, polycaprolactone, polyaminoacids, polyanhydrides, and half esters of methyl vinyl ether-maleic anhydride copolymers (3). [Pg.5]

Fig. 5.3 The IR spectrum of methyl vinyl ether-maleic anhydride copolymer represented by different number of FCs and HCs. The original consists of 512 intensity values. After the transformation, the coefficients are truncated step by step as shown in Fig. 5.2 the number of the remaining coefficients is shown beside respective steps. The reduced representations are then transformed back to 512 intensity values and plotted.

PVP forms molecular adducts with many substances. Insoluble complexes are formed when aqueous solutions of PVP are added to tannic acid, poly(acrylic acid) and methyl vinyl ether-maleic anhydride copolymer. Soluble complexes, called iodophors, are formed with iodine the solubility of iodine is increased from 0.034% in water at 25°C to 0.58% by 1% PVP. The resulting iodophor retains the germicidal properties of iodine. It is thought that the iodine is held in a PVP helix in solution. The influence of two samples of PVP on the solubility of testosterone is shown in Fig. 8.21. The PVP correspondingly increases the rate of solution of the steroid from solid dispersions. [Pg.300]

TWO organometallic polymers previously developed, tributyl-tin methaczylate/methyl methacrylate copolymer (TBTM/MeM) and the tributyltin ester of methyl vinyl ether/maleic anhydride (TBT-MVEt-MAn), were selected for use as wood impregnants. Full Cell and Enpty Cell Methods were used to treat wood with TBTCVMeM in "Rule 66" mineral spirits and in combination with P13 creosote. Although the polymers seem to be miscible with the creosote, this combination results in only surface penetration of wood when... [Pg.29]

Even though partially esterified copolymers of methyl vinyl ether-maleic anhydride copolymers were orignally designed to dissolve abruptly with an increase in external pH, in a constant pH environment they undergo a controlled dissolution process and are therefore useful materials for the controlled release of therapeutic agents dispersed within them (12),... [Pg.378]

The covalent bonding of antioxidant to a preformed polymer can also be prepared by chemical modification reactions such as the reaction of 3,5-di-t-butyl-4-hydroxybenzylamine with poly(methyl vinyl ether-maleic anhydride) under a basic condition to give the polymeric phenol-maleic acid derivative which on treatment with acetic anhydride gave the corresponding polymeric phenol-maleimide derivative (Scheme 5.9) [39, 53],... [Pg.259]

The poly(methyl vinyl ether/maleic anhydride) polymer is used as a thickener in many products such as lotions and creams, styling gels, and shampoos. This is available under the trade name Gantrez from GAP Corporation. The mechanism of thickening of this pol3rmer is similar to the polyacrylic acid polymers. The U.S. Patent 5385729 is an example of poly(methyl vinyl ether/maleic anhydride) polymer as a thickener in hair- or skin-treating gels [24]. [Pg.766]
