For each of the following pairs of polymers, plot and label schematic stress–strain curves on the same graph [i.e., make separate plots for parts (a) to (c)].
(a) Isotactic and linear polypropylene having a weight-average molecular weight of 120,000 g/mol; atactic and linear polypropylene having a weight-average molecular weight of 100,000 g/mol
(b) Branched poly(vinyl chloride) having a degree of polymerization of 2000; heavily crosslinked poly(vinyl chloride) having a degree of polymerization of 2000
(c) Poly(styrene–butadiene) random copolymer having a number-average molecular weight of 100,000 g/mol and 10% of the available sites crosslinked and tested at 20°C; poly(styrene–butadiene) random copolymer having a numberaverage molecular weight of 120,000 g/mol and 15% of the available sites crosslinked and tested at –85°C. Hint: poly(styrene–butadiene) copolymers may exhibit elastomeric behavior.
