Synthesis of α-hydroxyalkyl peroxide esters and ethers as initiators of radical processes
摘要:
alpha-Hydroxyalkyl peroxide esters and ethers containing, along with the peroxy bond, also acyloxy and alkoxy groups, are effective initiators of radical processes. The initiation efficiency is due to the capability of these molecules to generate simultaneously oxygen- and carbon-centered radicals capable of hydrogen abstraction from the substrate and of addition to > C=CaOE (c) bonds. The selectivity of the synthesis of alpha-hydroxyalkyl peroxide esters and ethers is mainly determined by the steps of the synthesis and isolation of the intermediate alpha-chloroalkyl peroxides, because of their high reactivity. Experimental conditions allowing control of the synthesis of alpha-hydroxyalkyl peroxide esters and ethers were found.
Cement admixture compositions formed from alkenyl ether/maleic anhydride copolymers having specific molecular structures have been found to impart a high degree of slump loss over a sustained period of time while not causing any significant set retardation of the treated cement based composition.
