Notes:
(a) Property values unless otherwise indicated were taken from O. G. Lewis, \"Physical Constants of Liner Homepolymers\", Springer-Verlag(1968)
(b) Property values not taken from (a)
A question mark indicates that apparently this value has not been determined
A dash indicates this property does not exist, e. q. atactic poly-styrene has no melting point since it is not crystalline
In every case the indicated name is not specific for the structure shown. For example, the term polycarbonate describes a class of materials, but the structure shown is usually the one implied when this term is used
The names listed in parenthesis under the chemical name is a more familiar name for this polymer, or it is a trademark when capitalized. Often the commercial material is actually a slight modification of this basic polymer, e. q. ACRILAN is a copolymer of acrylonitrile and vinylacetate but predominately the former.
Nylon is a generic name for polyamides, A numbering system describes the structure when they are prepared from aliphatic monomers, 1. e.
(1) N2N(CH2)xNH2 + HOOC-(CH2)y-COOH → Nylon x,y+2
(2) H2N-(CH2)x-COOH
NHCO → Nylon x+1
(CH2)x
