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).

Acrylonitrile-styrene-acrylate (ASA) constitutes a versatile member of the group of styrenic copolymers used for housings, covers and other applications which require excellent surface appearance and environmental stability combined with high impact resistance and stiffness. It consists of a poly(styrene-acrylonitrile) matrix modified with small rubber particles. [Pg.341]

Acrylonitrile is used in the production of acrylic fibers, resins, and surface coating as an intermediate in the production of pharmaceuticals and dyes as a polymer modifier and as a fumigant. It may occur in fire-effluent gases because of pyroly-ses of polyacrylonitrile materials. Acrylonitrile was found to be released from the acrylonitrile-styrene copolymer and acrylonitrile-styrene-butadiene copolymer bottles when these bottles were filled wifh food-simulating solvents such as water, 4% acetic acid, 20% ethanol, and heptane and stored for 10 days to 5 months (Nakazawa et al. 1984). The release was greater with increasing temperature and was attributable to the residual acrylonitrile monomer in the polymeric materials. [Pg.295]

Acrylonitrile-styrene-acrylate (ASA) copolymers is another family of graft-copolymer-based materials in which the rubber phase is really a copolymer of butyl acrylate (BuA) and butadiene (at least in some recipes) [47, 48], and the matrix is made of a SAN copolymer. Originally, butadiene was not present in the rubber phase [49] and perhaps those were not really graft-copolymer-based materials. The main advantage of ASA over ABS is its increased UV stability and long-term heat resistance due to the lack of residual double bonds in the acrylate part of the rubber. [Pg.210]

Considerable quantities of styrene are used in producing copolymerisates and blends, as, for example, in the production of copolymers with acrylonitrile (SAN), terpolymers from styrene/acrylonitrile/butadiene (ABS polymers) or acrylonitrile/styrene/acrylic ester (ASA), etc. The glass transition temperature of poly (styrene), 100 C, can be increased by copolymerization with a-methyl styrene. What are known as high impact poly (styrenes) are incompatible blends with poly(butadiene) or EPDM, which are consequently not transparent, but translucent. For this reason, pure poly (styrenes) are occasionally called crystal poly (styrenes). [Pg.406]

To this group of blends belong mixtures of PP with st)oene-elastomer copolymers, styrene-diene blocks styrene-butadiene-st)a ene (SBS), sty-rene-ethylene/butylene- t30 ene (SEBS), st)rrene-isoprene-styrene (SIS), with acrylonitrile-butadiene-styrene terpol)nners (ABS), acrylonitrile-styrene-acrylate (ASA), or with EPR/EPDM grafted with styrene and acrylonitrile (AES or AXS). The first blends of this type date from the early 1960s. In these systems, PP is either the main component to be modified, or an additive to enhance performance of the styrenic matrix. [Pg.624]

Styrene-acrylic copolymers were analyzed via NIR for styrene content using the 2100 nm aromatic C—H combination band [65]. Spectral characteristics of these blends are so distinct that no special sample preparation technique is required. NIR has also been applied for the compositional analysis of styrene-acrylonitrile (SAN), styrene-MMA, styrene/butadiene [15], AS in polyvinylchloride [66], and styrene-acrylic copolymers. [Pg.539]

Styrene-butadiene, acrylonitrile-butadiene, chloroprene, and vinyl chloride emulsion (co)polymers are mainly used in their dried form. Carboxylated SBR, VAc (co)polymers, acrylics, and styrene-acrylic copolymers are used, on the other hand, as binders of formulation for several industrial applications in their dispersed form. Figure 7 shows the share of each of these families and the major industrial applications of these latexes. ... [Pg.472]
