Question
Butene H2C=CH-CH2-CH3 can be reacted to form isotactic polybutene (PB).
(a) Would you expect isotactic polybutene to melt at a higher or lower temperature than atactic polybutene of the same molecular weight?
Higher T
Lower T
(b) Is isotatic polybutene a thermoplastic or thermoset?
Thermoplastic
Thermoset
(c) What is the value of the degree of polymerization n of isotactic PB with a molecular weight of 3.091×105 g/mol?
