Conclusions:
The glass transition temperature of Reaction products of 3-methyl-5-[(1S,4aS,8aS)-5,5,8a- trimethyl-2- methylenedecahydro-1-naphthalenyl]-1-penten-3-ol, cyclized was determined at -17.6 °C (255.5K) by using DSC.

Reaction and/or decomposition of Reaction products of 3-methyl-5-[(1S,4aS,8aS)-5,5,8a- trimethyl-2- methylenedecahydro-1-naphthalenyl]-1-penten-3-ol, cyclized was observed during DSC experiments at temperatures of > 125 °C (> 398K).
Executive summary:

Melting point Melting point was assessed using DSC at normal atmospheric pressure. The temperature during the test ranged from -90 to 309 °C.
