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?
(b) Is isotatic polybutene a thermoplastic or thermoset?
(c) What is the value of the degree of polymerization (n) of isotactic PB with a molecular weight of 3.091X10^5 g/mol?
a) Higher T
