To achieve high-performance thermosets from renewable resources, six acetovanillone-derived poly(aryl ether)s (two with the acetic moiety, two with the phenyl methacrylic moiety, and two with the vinyl benzyl ether moiety) were prepared. The poly(aryl ether)s with acetic- or phenyl methacrylic moiety were applied as epoxy curing agents to cure with a phenol-dicyclopentadiene epoxy resin (HP7200)....
To achieve high-performance thermosets, three diallyl-containing main-chain type benzoxazine polymers, (MCBP) were prepared from Mannich condensation of 2,2′-diallyl bisphenol A, paraformaldehyde, and three diamines: 4,4′-diaminodiphenylmethane (DDM), 4,4′-oxydianiline (ODA), and 2,2′-bis(4-(4-aminophenoxy)phenyl)propane (BAPP), respectively. These MCBPs can be cured and general a phenolic hydroxyl...
NORYL™ SA9000 resin is a commercialized telechelic PPO oligomer with phenyl methacrylate end groups. However, neat SA9000 thermoset is brittle after thermally curing. To find a method to enhance the toughness of neat SA9000 thermoset, three model reactions are designed. The first one is the 4-dimethylaminopyridine (DMAP)-catalyzed homopolymerization of glycidyl phenyl ether. The second one is the...
This article details electrochemical investigations of carbon paste electrode (CPE) modified with electroactive polyimide (EPI) as ascorbic acid sensor (vitamin C, AA). EPI, with aniline-pentamer-based in the main chain, was synthesized from oligoaniline and p-phenylenediamine by oxidative coupling polymerization. The well-defined molecular structure of the oligoaniline and EPI was confirmed by LC-Mass,...
