Abstract: Title resin with high mol. wt., low content, and high m. p., was prerd. by treating xylene with HCHO in the presence of an acid catalyst in a closed reaction vessel in the absened of air. Thus, 212 g m-xylene and 63.15 g p-formaldehyde were heated in a closed reaction vessel in the absence of air to 900C, mixed with 9.19 g HCIO4 and heated 3 hr while water was removed, giving after purifn. a polymer with softening point 1650C, glass temp. 1230C, mol. wt. 20,400, Gardner color 2, Brabender plasticorder torque at 35 rpm 830-650 mg after 13 min at 1800C, intrinsic viscosilty 0.12, and shore D hardness 84.
