Document Type and Number:
Japanese Patent JP5721519
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a phenolic polymer having flame retardancy and softening point in the same level as in conventional phenol aralkyl resins; and to provide a composition thereof and a method for producing the same.SOLUTION: The phenolic polymer is obtained by reacting phenols represented by formula (1), an aromatic compound represented by formula (2), and a condensate of m-xylene/formaldehyde/methanol under the conditions in which the molecular ratio of the aromatic compound to the phenols is 0.10 to 0.20; and the condensate of m-xylene/formaldehyde/methanol having an oxgen content of 10 to 20 wt.%, a viscosity at 25°C of 70 to 150 mPa s, and a number-average molecular weight of 200 to 350 is used in 35 to 50 wt.% to the weight of the phenols. In the formula (1), Ris a hydrogen atom, a 1-6C alkyl group or an aryl group, and in the formula (2), X is a halogen, an OH group or an OCHgroup.
