Density |
Isocyanates...are highly reactive and undergo addition reactions across the carbon-nitrogen double bond of the NCO group. Reactions with alcohols, carboxylic acids, and amines have been widely exploited...The basis for the high reactivity of the isocyanates is the low electron density of the central carbon...Electron withdrawing or donating substituents alter the electrophilic nature of the isocyanate...The reactivity of the isocyanates is also manifested in their tendency to react with themselves to form dimers, trimers, or higher oligomers and polymers. /Isocyanates/ |
