PURPOSE:To obtain the titled composition capable of keeping workplace environment clean in its production and/or use, enabling working efficiency to be improved and the cost of pollution control equipment to be reduced, by incorporating powdery phenolic resin with specific ester compound and/or oils. CONSTITUTION:The objective composition can be obtained by incorporating (A) 100pts. by wt. of powdery phenolic resin with 0.3-3wt% of (B) at least one kind of liquid ester compound with a boiling point >=200 deg.C selected from phosphoric esters and both aliphatic and aromatic carboxylic acid esters and/or (C) oils. The process is as follows: the component B and/or the component C is mixed, in advance, with a powdery material vivtually incompatible therewith followed by with the component A, then carrying out a cogrinding. Said powdery material is, e.g., hexamethylene-tetramine, calcium carbonate. |
