In most cases the polymer is dissolved in special solvents and spun into acrylic fibres, which are defined as fibres that contain 85 percent or more of PAN. On the other hand, a copolymer containing 2 to 7 percent of a vinyl comonomer such as vinyl acetate can be solution-spun readily to fibres that soften enough to allow penetration by dyestuffs. Since PAN softens below its thermal degradation , processing of poly acrylonitrile must be done by wet or dry spinning rather than melt spinning . Pure PAN can not be dye and therefore … Other applications include packaging for food, agricultural chemicals and medicines (Brazdil, 1991). Poly Propenenitrile (Acrylic) How can the monomer used to make an addition polymer be identified from the polymer. These fibres can be stretched to several times their original length and are known under the name: “acrylics”. Its semi-crystalline nature offers high flexural strength too, making it resilient to general wear and tear and ideal for items that must undergo higher levels of physical stress.

These are produced by pyrolysis of oriented polyacrylonitrile fibres and are used HDPE is High Density Poly(Ethene) and has a higher crystallinity and a higher melting point than LDPE (Low Density Poly(Ethene). This low melting point also means that polypropylene is highly flammable and limited in its ability to withstand higher temperatures and it is also susceptible to UV degradation and oxidation. PAN has none of the hazardous properties of the monomer. Polypropylene has high insulation properties too, making it safe to use for plastic casing in electrical goods and cables. A particularly preferred polymer or copolymer of 2-propenenitrile and 2-methyl-2-propenenitrile in the purview of this invention is the saponified copolymer of poly(2-propenamide-co-2-propenoic acid) (the sodium salt thereof.) Production Propenenitrile (acrylonitrile) is produced from propene and ammonia. It flows well too, due to its low melt viscosity. Acrylonitrile (a.k.a. Going back to the drawing board, polystyrene also serves as the base component in styrene-acrylonitrile (SAN), a copolymer of styrene and acrylonitrile, sometimes known as propenenitrile.
