Abstract
A preparation method of an oligomer-polymer is provided. A maleimide is reacted with a barbituric acid to form a first oligomer-polymer. The first oligomer-polymer is then reacted with a phenylsiloxane oligomer to form a second oligomer-polymer. The phenylsiloxane oligomer is a compound represented by formula 1:Ph-Si(OH)xOy formula 1,wherein x is 0.65 to 2.82 and y is 0.09 to 1.17.
