摘要： Disclosed is a novel polyorganosiloxane having a specific structure and excellent curability. Also disclosed is a curable composition exhibiting good workability during a curing process which enables to obtain a cured product that is excellent in ultraviolet transmittance and heat resistance while being improved in toughness and crack occurrence due to cooling/heating cycles. The polyorganosiloxane has an oxetanyl group, and is obtained through hydrolysis-condensation of an organic silicon-containing compound represented by the general formula (1) below in the presence of an organic polyol compound having two or more hydroxyl groups.

摘要： The object of the present invention is to provide a polyorganosiloxane that has a specific structure and is superior to curability and a curable composition which is high in workability during curing, which leads to a cured product excellent in ultraviolet-ray transparency and heat resistance, and further wherein toughness thereof and occurrence of a crack by cyclic heat-cool are improved. The present polyorganosiloxane is one obtained by conducting hydrolysis and condensation of a silicon-containing organic compound represented by the general formula (1) below in the presence of an organic polyol compound having two or more hydroxyl groups and has an oxetanyl group.
