The chemistry of fast‐curing phenolic adhesives. II
Journal of Applied Polymer Science, 1973 AbstractNovolak‐like materials have been prepared by reaction of phenol–formaldehyde resoles with aromatic amines. The hydroxymethyl groups present in resoles react with the ring carbons and the amino groups of the aromatic amine. Proportions of the two types of product vary with the amine used.

The chemistry of new latent curing systems for epoxy resins
Journal of Applied Polymer Science, 1961 New types of catalyst combinations for epoxy resins are described and examples given. These combinations consist of a triethanolamine-chelated titanium compound or phosphorus compound and a borate ester which react to give triethanolamine borate and other epoxy-reactive products.

A review of nitrite and chloride chemistry: Interactions and implications for cured meats
Journal of the Science of Food and Agriculture, 1985 AbstractConcerns for the health‐related implications of sodium nitrite and sodium chloride in cured meats have lead to reductions in use of both ingredients and there is evidence of chemical interaction between nitrite and chloride in food systems which have implications for cured meats.

The Chemistry of the Zinc Oxide Cure of Halobutyl
Rubber Chemistry and Technology, 1984Abstract The studies described in this papier lead to certain conclusions. The crosslinking reaction of halobutyl with zinc oxide does not give rise to ether crosslinks. All the evidence indicates that the chemistry involves the formation of carbon-carbon bonds by an alkylation type chemistry.

INSIGHTS INTO THE CURE CHEMISTRY OF BROMINATED BUTYL RUBBER
Rubber Chemistry and Technology, 2019ABSTRACT The importance of dehydrobromination to the cure chemistry of brominated butyl rubber (BIIR) is demonstrated through a combination of cure rheometry studies and model compound experiments. These data show that, while HBr elimination to give an exomethylene conjugated diene is inevitable, subsequent reactivity is highly sensitive to ...

Studies on cure chemistry of new acetylenic resins
Macromolecules, 1993Cure studies of arylacetylene-terminated resins are described to gain some fundamental understanding of the influence of various structural aspects of a molecule on its cure chemistry. Of particular interest are the effects of the number of acetylenic substituents on the aromatic ring and their relative positions to one another.

The chemistry and applications of UV-cured adhesives
International Journal of Adhesion and Adhesives, 1991Abstract The chemistry involved in ultra-violet (uv) curing can be divided into two types: free radical and cationic. The more common formulations are cured by free radical polymerization of acrylate functional resins. Cationic polymerization involves the formation of a Bronstead or Lewis acid during the UV initiation which can then polymerize such ...
