Dicyclopentadiene phenol resin(DPR) was prepared from dicyclopentadiene and phenol with methane sulfonic acid as the catalyst.The optimum conditions for the synthesis were as follows:n(phenol)/n(DCPD)=5;w(catalyst)=1.5%;temperature=120℃;time=5 h;yield=89%.The light yellow dicyclopentadiene phenol resin was obtained by the decolouring of catalytic-hydrogenation.The optimal conditions for the decolorization were as follows:hydrogen pressure=1.5 MPa,w(Pd/Al2O3)=0.5%,temperature=80℃,yield=89%.FT-IR and 1H NMR analysis identified the desired product.The product properties reached the international quality standards.
