Abstract
PURPOSE: A mixture of an aromatic polyester and an organic compound that is incompatible with the aromatic polyester and soluble in an alkaline solution is formed, heat treated at a specific temperature, treated with an alkali and beaten to produce the titled pulp including uniform and fine fibrils.
CONSTITUTION: A mixture of a linear aromatic polyester and an organic compound that is incompatible with the polyester and soluble in an alkaline solution such as an organic sulfonate metal salt is formed. The resultant product is heat treated at a temperature given by the equation [Ta is the softening point of the organic compound (°C); T is the heat-treatment temperature (°C); Tp is the softening point of the linear aromatic polyester (°C)] and treated with an alkaline solution, finally beaten. The diameter of the resultant fibrils is vey small and uniform and the pulp shows very good paper-making properties.
