An investigation was made of the interaction of new heat-resistant boron-containing polymers (polyesters of phenols and boric acid) with epoxy resin. A mechanism of this interaction is proposed, consisting in the formation of bonds between carbon of the epoxy group and carbon located in the o-position of phenyl radicals of the polymers.
Durch KOH katalysierte Additionen von Acetylen an die Hydroxymethyltriazole (I) liefern die Vinylether (II); analog erhält man aus 2‐Ethyl‐4,5‐bis‐(hydroxymethyl)‐l ,2,3‐triazol den Bisether (III) sowie aus den Triazolen (VIII) und (X) Gemische der Ether (IX) und (Va) mit den Dehydratisierungsprodukten (VII) bzw. (XI).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
