Acrylonitrile—methyl acrylate—iadene terpolymers, by themselves, or ia blends with acrylonitrile—methyl acrylate copolymers, exhibit even lower oxygen and water permeation rates than the iadene-free copolymers (110,111). Terpolymers of acrylonitrile with iadene and isobutjlenealso exhibit excellent barrier properties (112), and permeation of gas and water vapor through acrylonitrile—styrene—isobutjleneterpolymers is also low (113,114). [Pg.196]

General Description Intended primarily for packaging use, acrylonitrile-based resins are sometimes called barrier resins. Acrylonitrile-Methyl-Acrylate Copolymer (AMA) is a clear, rubber-modified acrylonitrile with excellent chemical resistance and gas barrier properties, as well as a high modulus or stiff-ness.f ]... [Pg.9]

Other acrylonitrile copolymers have found specialty applications with good gas-barrier and chemical-resistant properties. An example is BP Chemicals Barex resins which are acrylonitrile-methyl acrylate copolymers grafted on a nitrile rubber. Barex resins are unique barrier resins with the combinations of excellent oxygen barrier, good chemical resistance, and antiscalping properties. [Pg.226]

Brar and Sunita [184] have reported the reactivity ratios (r) for the acrylonitrile]A)-methyl acrylate (M) monomer pair using the errors in variables model (EVM) [185, 186] with the use of a computer program written by O Driscoll and co-workers [187]. The primary structure factors monomer composition, diad/triad sequence distribution, conditional probabilities, and number-average sequence lengths of acrylonitrile-methyl acrylate copolymers were determined on the basis of C H -NMR analyses and compared with those calculated from reactivity ratios as determined from EVM program. The diad sequence calculated from C H)-NMR (proton decoupled C-NMR) spectra was correlated with the Tg of A/M copolymers. [Pg.238]

VA content in copolymer increases sharply with conversion in acrylonitrile-vinyl acetate copol merization (i i/iJ2 = 4.05/0.061) and content of MA in copolymer changes very little with conversion in acrylonitrile-methyl acrylate copolymerization (i i/i 2=l 02/0.70). [Pg.831]

Important copolymers of styrene are SBR (styrene butadiene rubbers), ABS, a copolymer with butadiene and acrylonitrile, and various copolymers with methacylic and acrylic esters, such as styrene-methyl methacrylate and styrene-methyl acrylate copolymers. Additionally, copolymers formed with one or more of the following monomers also exist ethylene, a-methyl styrene, vinyl acetate, maleic anhydride, and acrylonitrile. [Pg.257]

Copolymers that have been investigated include acrylonitrfle-cr-methyl-styrene, acrylonitrile-methyl acrylate, acrylonitrile-methyl methacrylate, acrylonitrile-vinyl acetate, acrylonitrile-vinyl bromide, acrylonitrile-acrylic acid, and acrylonitrile-lV-vinylpyrrolidone. As might be expected the course of the thermal decomposition is significantly affected by the presence of a comonomer some accelerate the cyclization of acrylonitrile sequences, whilst others inhibit the process. [Pg.314]
