Results and discussion
Any other information on results incl. tables
As major products of the degradation, the monomer, 2-propanal, methacrylic acid, 1,2-propandiol, 2-(2-propenyloxy) propyl methacrylate, 2-hydroxpropanal, and hydroxymethyl isopropyl ether were detected.
Applicant's summary and conclusion
- Conclusions:
- The thermal decomposition of Poly(HPMA) was investigated by a study with two stages which are from ambient temperature to 340 °C and in the region of 340-450 °C. The data indicate that the overall degradation process consits of two reactions as the major reactions: depolymerization to monomer and side-group scission.
