Question
Reactivity ratios in this equation may be calculated via the Kelen-Tüdős method or predicted by the Q-e scheme. For 10 points each:
[10h] Name this equation that describes the distribution of monomers M-sub-one and M-sub-two in a copolymer.
ANSWER: Mayo-Lewis equation
[10m] When reactivity ratios are both larger than 1, the Mayo-Lewis equation predicts the formation of this class of copolymer. These copolymers comprise two or more covalently linked homopolymers.
ANSWER: block copolymers
[10e] When both reactivity ratios are less than 1, the feed and copolymer compositions are identical, forming one of these mixtures. These solutions violate Raoult’s law and cannot be separated by distillation.
ANSWER: azeotrope
