Synthesis of reactive polyesters by a regioselective addition reaction of diepoxides with diacyl chlorides and their chemical modification

Synthesis of poly(cyanurate)s by a novel polyaddition of bis(epoxide)s with triazine dichloride

“…From these results, DPAT can be categorized as a number of the active reagent family relating to the epoxide groups, as is an acyl chloride. 11 Both of them react with bis(epoxide), producing the corresponding poly(cyanurate) and poly(ester) under similar reaction conditions.…”

New Acyl-Group Transfer Polymerization of Thiiranes Using Carboxylic Acid Derivatives and Quaternary Onium Salts

“…28, No. 1,1996 polymerization of thiiranes base on the regioselective addition reaction of thiiranes with carboxylic acids derivatives. The polymerization was achieved using active carboxylic acid derivatives such as acyl chlorides and S-thioesters as initiators and quaternary onium salts as catalysts.…”

“…1 The concept of group transfer polymerization is that a functional group transfers at a growing chain terminal in each propagation step to give a living polymer. Many studies on the group transfer polymerization of various methacrylates 2 • 3 including mechanistic investigations 4 • 5 have been reported for a decade.…”

Novel Synthesis of Polymers with Well-Defined Structures Based on Selective Reaction of Cyclic Sulfides and Cyclic Ethers Catalyzed by Quaternary Onium Salts

“…For example, photo-functional poly-(ester)s with norbornadiene moieties in the side chains were prepared by the reaction of the aforementioned reactive poly(ester) with potassium 3-phenyl-2,5-norbornadiene-2-carboxylate using phase transfer catalysts. 26 We also successfully synthesized multifunctional photosensitive polymers with posi- A. KAMEYAMA and T. NISHIKUBO tive-working groups in the main chain and negative-working groups in side chains. 40 Reactive polyester containing a cyclobutane ring in the main chain and pendant chloromethyl groups was prepared by the polyaddition of bis(epoxide)s with -truxiloyl chloride.…”

“…The regioselective polyaddition of bis(epoxide)s with diacyl chlorides provided poly-(ester)s with pendant chloromethyl groups, and high molecular weights. 26 The regioselective polyaddition of bis(epoxide)s with active aromatic dichlorides also provided reactive poly-(ether)s with pendant chloromethyl groups. 27 The polyaddition of bis(epoxide)s with bis(chloroacetoxy)esters or bis(bromoacetoxy)esters proceeded regioselectively to give poly(ether)s with pendant halomethyl groups.…”
