The most toxic, gaseous combustion products of polyacrylonitrile are to be stated. Concept introduction: The polymers (repeating structural units) are derived from the simple and reactive molecules, called as monomers. Polyacrylonitrile (PAN) is a synthetic polymer formed by the addition polymerization of acrylonitrile. It is a hard thermoplastic material and its combustion lead to the formation of gaseous substance that is highly toxic if ingested and known as carcinogens. To determine: The toxic, gaseous combustion products of polyacrylonitrile.

Solution Summary: The author explains that polyacrylonitrile is a hard thermoplastic material and its combustion lead to the formation of gaseous substance that is highly toxic if ingested.
Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.
