WebSep 7, 2024 · Melting is the transition between a crystalline solid and a liquid. The melting point of a small molecule is very well-defined at a given pressure. Water, for instance, melts at 0 o C when P = 1 atm. Polymers, on the other hand, do not have a single well-defined melting point. When a polymer "melts" it slowly becomes "leathery," then "tacky ... WebJul 9, 2024 · Acrylic fibers are synthetic fibers made from a polymer (polyacrylonitrile) with an average molecular weight of -100,000, about 1900 monomer units. For a fiber to be called "acrylic" in the US, the polymer must contain at least 85% acrylonitrile monomer. Typical comonomers are vinyl acetate or methyl acrylate.
