WebIf your polymer is a high molecular weight polymer that has lung overloading potential. Unless your polymer is in human health hazard band C or B, the human health hazard band is A if your polymer is all of the following: has a number average molecular weight that is greater than 70,000g/mol; has a solubility in water of less than 0.1mg/L WebFurther, because of their widespread use, a limited number of well-established traditional polymer names are retained outside the systems of source-based or structure-based nomenclature , . Table 8 compares and contrasts structure-based, source-based, and retained traditional names for some common polymers.

WebNov 9, 1993 · The Polymer Age is also called the Age of Plastics. "Plastic" (from the Greek "plastikos," meaning moldable) is the popular term for a variety of synthetic, or manmade, polymers. Polymers ("poly" = many) are very large molecules—veritable giants in the molecular world—comprised of smaller molecules called monomers ("mono" = one).
