“…The propagation reaction is a nucleophilic attack by another monomer. Different pathways are possible in the ring opening of SOEs, [18] leading some of them to the formation of g-BL, being the most probable of these pathways represented in Scheme 3. The g-BL generated in this reaction may in turn reacts with epoxy to get a new SOE group, what agrees with the decrease in the g-BL conversion observed for all the systems studied.…”

“…All catalysts listed in Table 2 including Lewis acids, onium salts, and phosphine derivatives were commercially purchased and used without further purification. SOEs (SOE-I-VII, IX, XI-XV) in Table 1 were prepared according to the literature in 11-66% yields [13,14]. Almost all the acid chlorides, acetic anhydride, and benzyl chloride listed in Table 4 were reagent grade, and used without further purification.…”

“…According to the reported cationic mechanism of the reaction [14], two groups of reagents for the cationic reaction were tested as the catalysts: (1) Lewis acids and derivatives and (2) onium salts. The reaction of monofunctional SOE, 2-methoxymethyl-1,4,6-trioxaspiro [4,5] decane (SOE-II), and benzoyl chloride (BC) was carried out in the feed ratio [SOE]:[-COCl]Z1:1 with catalysts of approximately 0.5 or 3 mol% based on [SOE] at 100 8C for 2 h in bulk.…”

“…Las reacciones de curado, ya sea por adición o por condensación, presentan el problema de la contracción [133] debido a que las moléculas se encuentran separadas por distancias Van der Waals y al polimerizar pasan a ser distancias covalentes, más próximas entre sí [134][135][136].…”
