Abstract
Novel propargyl esters are prepared by a base catalyzed condensation reaction of propargyl esters of carboxylic acids containing a labile hydrogen atom at the alpha position relative to the carboxy group, and a terminal aromatic hydrocarbon radical that is linked to the carboxy group through a sequence of carbon atoms containing at least one carbon-to-carbon double bond. If more than one of these double bonds are present they form a conjugated sequence. Novel organosilicon compounds are prepared by reacting these propargyl esters with an organohydrogensilane or an organohydrogensiloxane. The organosilicon compounds undergo a reversible crosslinking reaction in the presence of ultraviolet light.
