In order to enhance the compatibilization and interfacial adhesion between epoxy and liquid carboxyl-terminated butadiene acrylonitrile (CTBN) rubber, an initiator was introduced into the mixture and heated to initiate the cross-linking reaction of CTBN. After the addition of curing agents, the CTBN/epoxy blends with a localized interpenetrating network structure were prepared. The mechanical p...

A series of C4-C 12 alkyl acrylates and methacrylates was polymerized with starch by irradiating starch-monomer mixtures with 60CO. Homopolymers were extracted with cyclohexane. The amounts of insoluble versus soluble synthetic polymer in polymerizations run with alkyl acrylates varied less with the chain length of the alkyl substituent than in the polymerizations run with alkyl methacrylates: ...

The adhesion behavior of statistical, uncrosslinked butyl acrylate-methyl acrylate copolymer on different surfaces (stainless steel, polyethylene, glass and Si-wafer) has been investigated using a combination of probe tack test and simultaneous video-optical imaging. Tack and stress peak values increase and the final number of cavities as well as cavity growth rate decreases with increasing sur...

This article presents a computational study of chain transfer to monomer (CTM) reactions in self-initiated high-temperature homopolymerization of alkyl acrylates (methyl, ethyl, and n-butyl acrylate). Several mechanisms of CTM are studied. The effects of the length of live polymer chains and the type of monoradical that initiated the live polymer chains on the energy barriers and rate constants...

Photolysis of dibenzyl ketone derivatives adsorbed on ZSM-5 zeolites produces persistent benzyl radicals (initiator radicals), which add to methyl acrylates (monomers) to generate persistent adduct radicals. Both initiator and adduct radicals are readily observable by conventional steady-state EPR spectroscopy at room temperature and are persistent for time periods ranging from seconds to many ...

Manufacturing materials are an essential element for the fabrication of microfluidic chips. PDMS, the most widely used polymeric material, is associated with apparent disadvantages such as hydrophobic nature, while other materials also suffer from some limitations. In this paper, a new soft lithographic route was proposed for the facile manufacturing of hydrophilic sandwich microchips, using bi...

Copyright © Korean Carbon Society http://carbonlett.org Abstract The use of carbon nanotubes (CNTs) as a reinforcing material in a polymer matrix has increased in various industries. In this study, the flexural behavior of CNT-modified epoxy/ basalt (CNT/epoxy/basalt) composites is investigated. The effects of CNT modification with silane on the flexural properties of CNT/epoxy/basalt composite...

Inside Cover: In article 2200586, Sandra Schlögl and co-workers demonstrate that Acrylate functional coumarin monomers are synthetized cured by wavelength orthogonal photoreactions yielding soft (405 nm) stiff (365 networks. Advancing from thin films, the dual 3D printing of active devices is demonstrated with locally controlled mechanical thermal properties using a single vat. The concept high...
