Embodiment Construction
[0039] Specific embodiments of the present invention are described in detail below in combination with technical solutions (Table 1-3). Among them, Table 1 relates to the alternating copolymerization reaction of trivalent metal complexes catalyzed carbon dioxide and epoxycyclohexane; Table 2 relates to the alternating copolymerization reaction of trivalent metal complexes catalyzed carbon dioxide and epoxycyclopentane; Table 3 relates to divalent metal complexes The complex catalyzes the alternating copolymerization reaction of carbon dioxide and alkylene oxide.
[0040] In a 100mL stainless steel autoclave, add in the following order at ambient temperature: a certain amount of main catalyst (any metal complex described in the first article of the claim), cocatalyst R 1 R 2 3 YX 1 (if necessary), then pump 20mL alkylene oxide into the sealed autoclave respectively, feed carbon dioxide gas, and rapidly rise to the set temperature, and keep the carbon dioxide pressure in the ...
