Notes:
The thermal polymerization of dihydro-exo-dicyclopentadienyl acrylate (DDA) (tricyclo[5.2.1.02.6]dec-3-en-9-yl acrylate) was carried out under nitrogen in the absence of any initiator to investigate the kinetics and mechanism for it. The polymerization rate was found to follow the equation: Rp=k[DDA]1.6. The rate was nearly the same as those obtained for the polymerization of other alkyl acrylates. The overall activation energy for the polymerization was determined to be 57,3 kJ/mol (13,7 kcal/mol). The kinetic data and the data obtained by spin trapping technique during the polymerization showed that the double bond of the acryl group was polymerized much faster than that of the cyclopentene ring to form the straight chain polymer and that the double bond of the cyclopentene ring began to polymerize to a small extent, at a stage where most of acryl groups were polymerized, to give some crosslinking structures.
