Abstract
The thermal degradation of poly(2,2-dialkyl-3-propiolactones) (I) has been studied. By comparing the thermal degradation of capped (methyl esterified) and uncapped (carboxylic acid terminated) polymer, it is demonstrated that above ∼350°C, I degrades by unzipping from carboxylic acid termini. Random scissions can generate chains with carboxylic acid termini. Capped I requires random scission generation of carboxylic acid termini before polymer unzipping can ensue. One random scission process elucidated requires the presence of a C-H group at the 2 position of one of the alkyl side groups in I and generates two distinguishable chains
