ABSTRACT:
The process according to the present invention comprises a continuous polycondensation of the anthracene fraction of coal tar boiling within the range of from 270.degree. C. to 350.degree. C., phenol and formaldehyde at a weight ratio between the components of 1:3-4:1-1.2 in the presence of 0.5 to 1.2% by weight of an acidic catalyst at a supply rate of a mixture of said components of 500-550 g/hr.
The present invention makes it possible to continuously prepare the desired product, whereby its output from a unit production volume is substantially increased. The product has a high curing rate and a high coke value.
