Styrene-acrylonitrile copolymer abbreviation

If two monomers are used to make a plastics material then, the resultant product is known as a copolymer. It may be referred to by means of initials which represent the monomers used i.e. without a p for poly . For example, the copolymer (bipolymer) made from styrene and acrylonitrile, is referred to as styrene acrylonitrile copolymer or, as SAN. It is now suggested that an oblique stroke / be placed between the two monomer abbreviations e.g. E/P for an ethylene propylene copolymer. However, this suggestion is not universally adopted as SAN is still SAN the oblique strokes may be omitted when common usage so dictates according to ISO 1043-1 1987 (E).

Figure 1 Cost-related (specific) flexural strength of major thermoplastics, versus cost-related (specific) thermal tolerance. The unit cost is the market price in US cents (1992) of 1 cm plastics. The thermal tolerance is the temperature difference (AT) over room temperature (AT — T - room T), by which temperature (7 ) the flexural modulus is equal to 1 GPa.
