Difficult to say for PU and PCL because polymers typically decompose before they reach their theoretical boiling point. DMF has a boiling point of 153o C and a vapor pressure of 516 Pa.

yes agree with @jack murph, it is difficul to say B.P of Polymers because it varies according to their molar masses as the molar masses increase they change their physical state from liquid to solid. So first u have to check molar mass of your polymers.

Polymers have neither boiling points nor vapor pressures.

When polymers are formed, the large molecules "macro molecules" will have many inter-molecular attractive forces "the secondary bonds which could be London forces, dipole-dipole interactions, and hydrogen bonding".

The cumulative effect of these 2o bonds will amount to the strength of several primary bonds. Therefore, when polymers are subjected to strong heating, they decompose before they volatilize "i.e. there will be no boiling & no vaporization".

Thank you sir
