WebbThese polymers—all containing pendant double bonds—undergo important photoinduced loss of unsaturation, presumably through cyclization of the double bonds, by analogy to the previously reported photocyclization of 1,2-polybutadiene (VB) and 3,4-polyisoprene (VI)films.For the equibinary polymers, which contain internal as well as external (or … WebbResults: The amount of residual double bonds in the hybrid layer varied from 10 to 25% compared to the uncured adhesives, a relatively higher percentage was detected for …

In chemistry, a double bond is a covalent bond between two atoms involving four bonding electrons as opposed to two in a single bond. Double bonds occur most commonly between two carbon atoms, for example in alkenes. Many double bonds exist between two different elements: for example, in a carbonyl … Visa mer The type of bonding can be explained in terms of orbital hybridisation. In ethylene each carbon atom has three sp orbitals and one p-orbital. The three sp orbitals lie in a plane with ~120° angles. The p-orbital is perpendicular to this … Visa mer In molecules with alternating double bonds and single bonds, p-orbital overlap can exist over multiple atoms in a chain, giving rise to a conjugated system. Conjugation can be … Visa mer Double bonded compounds, alkene homologs, R2E=ER2 are now known for all of the heavier group 14 elements. Unlike the alkenes these … Visa mer Webb14 dec. 2015 · A double bond is formed when two atoms share two pairs of electrons. The sharing of two electrons is known as a covalent bond.
