The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. 110661-91-1, Name is tert-Butyl 4-bromobutanoate, SMILES is O=C(OC(C)(C)C)CCCBr, in an article , author is Zeng, Yanning, once mentioned of 110661-91-1, Formula: C8H15BrO2.
Fabrication and curing properties of o-cresol formaldehyde epoxy resin with reversible cross-links by dynamic boronic ester bonds
Conventional cured o-Cresol Formaldehyde Epoxy Resin (o-CFER) with permanent crosslink network is relatively stiff, brittle, and unrecyclable. In order to overcome these defects, herein 2,2′-(1,4-phenylene)-bis [4-mercaptan 1,3,2-dioxaborolane] (BDB) is employed as curing agent and a novel type of covalent adaptable network o-CFER is constructed by the reaction between thiols in BDB and epoxy groups in o-CFER. Obtained curing o-CFER vitrimers possess superior thermostability and good mechanical properties. Because of the transesterification of boronic ester bonds, o-CFER network topologies can be altered, contributing a self-healing ability and shape memory to the produced polymer. Besides, it is investigated the effects of the healing time and temperature on self-healing capability and achieved a healing efficiency of above 95% at 160 degrees C for 12 h. Moreover, through hot press, the pulverized samples of 8%C-o-CFER can be reshaped several times and mechanical properties of the recycled samples are well-restored even higher than those of pristine after being remolded at 200 degrees C for 60 min.
