Lopattananon et al. (2007) have prepared blends of maleated natural rubber and carboxylated nitrile rubber in the presence of zinc acetate to form a compatibilizing copolymer through ionic cross-links. The effect of different maleation levels was studied. Blend properties were compared to those for blends with unfunctionalized rubbers. [Pg.619]

In addition, the compatibility of natural rubber and poly(methyl methacrylate) blends was improved by modification of the functional groups of the natural rubber molecules to be more hydrophilic. Nakasorn and coworkers synthesized maleated natural rubber by using maleic anhydride. Grafting maleic anhydride onto the backbone of the non-polar natural rubber overcame the disadvantage of the low surface energy of natural rubber. This improved the... [Pg.325]

The Mooney viscosity value of the maleated natural rubbers/poly(methyl methacrylate) blends increased with an increased concentration of maleic anhydride used in the grafting copolymerization. The shear flow property of the... [Pg.339]

To further improve the interaction between the modified clay and polymer matrix, a compatibilizer is used, which is compatible with the polymer matrix but at the same time more polar than the matrix. Epoxidized natural rubber and maleated natural rubber" are among the common compatibilizers used in natural rubber-clay systems. [Pg.392]

Two types of NR (ADS and STR 5L) were used to prepare maleated natural rubber (MNR). Melt rheological properties of MNRs i.e. MNR-ADS and MNR-STR 5L) and their blends with various blend ratios were investigated. Two sets of rubber blends including MNR-ADS and MNR-STR 5L were prepared using a two-roll mill at a mixing temperature of 60 °C. Mastication of... [Pg.437]

Isobutyl acetate [110-19-0] is a colorless, neutral liquid with a pleasant, fruity odor. It is miscible with organic solvents, but immiscible with water. Isobutyl acetate has a high solvency for cellulose nitrate, colophony, damar resin, ketone and ketone-formaldehyde resins, maleate resins, urea and melamine resins, and phenolic and alkyd resins. Polymers such as polystyrene, poly(vinyl ethers), poly(vinyl acetate), polyacrylates, chlorinated rubber and vinyl chloride copolymers, as well as fats, greases, and oils are readily dissolved. Postchlorinated poly(vinyl chloride) is less soluble. Polyisobutene, cellulose ethers, polymethacrylates, poly(vinyl butyrals), natural rubber, and manila copal are swollen. Shellac, cellulose acetate, cellulose acetobutyrate, poly(vinyl chloride), and poly(vinyl formal) are insoluble. [Pg.363]

In another study by Cherian et UPA was modified by blending with functionalized rubbers such as ENR, hydroxyl-terminated natural rubber, and maleated nitrile rubber. The elastomers bearing reactive functional groups showed better compatibility with the resin and improved the toughness and impact resistance of the cured resin substantially, compared to unmodified elastomers. Maleated nitrile rubber (NBR) was far superior to all other... [Pg.364]

In 1939 Bacon and Farmer showed that the reaction between c/s-1,4-polyisoprene (natural rubber) and maleic anhydride was accelerated by benzoyl peroxide and they originally suggested that the anhydride linked across adjacent double bonds (intramolecular reaction) or across non-adjacent double bonds (usually intermolecular reaction). They also observed that when the concentration of rubber in the solvent used for the reaction exceeded a few per cent the product gelled and became insoluble. In subsequent work in which the model system cyclohexene-butyl maleate was studied Farmer (1942, 1943) revised his earlier suggestions and concluded that reaction was more likely to be at the ally lie (a-methylene) carbon.

Over the years there has been some interest in vulcanized maleated polyisoprenes because of their superior solvent resistance, flex cracking resistance and ageing resistance compared with conventional natural rubber vulcanizates. However where these properties are of importance there are other readily available polymers such as plasticized PVC, ethylene-vinyl acetate copolymers and the rubbery polyurethanes which may be more suitable. For this reason the maleated rubbers have not become of any commercial significance. [Pg.186]
