Oxirane, methyl-, polymer with carbon dioxide

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: After fixing a chain transfer agent to control a molar fraction of —COOH group to 45 relative to a molar fraction of the catalyst and then introducing adipic acid, 5.9 mg (Entries 1 to 5); tricarballylic acid, 5.1 mg (Entries 6 to 10); 1,2,3,4-butane tetracarboxylic acid, 4.7 mg (Entries 11 to 15)) into a reactor, vinylcyclohexene dioxide was weighed to numeral values listed in TABLE 3, relative to the molar fraction of the catalyst and then introduced (into the reactor). Then, polymerization was executed and the catalyst was removed according to the same procedures as described in Example 1, resulting in pure copolymer. TABLE 3 summarizes results of the polymerization. FIG. 2 shows GPC curves of a copolymer obtained by carbon dioxide/propylene oxide copolymerization in the presence of tricarballylic acid (C3H5(CO2H)3) and diepoxide, wherein reference numeral in each curve denotes an entry number in TABLE 2. introduced (into the reactor) Then, polymerization the catalyst was removed resulting in pure copolymer TABLE 3 summarizes results of the polymerization
