| Abstract | ||
| In this work different types of phenolic resins were synthesized from many substituted phenols such as P-N,Ndiethylamino phenol and m-N,Ndiethyl amino phenol and 1,8-DihydroxyNaphthaline with formaldehyde, the linier polymers (P1-P3)and crosslinked polymers (Ps,Pa) were obtained, and characterized by IR spectroscopy and thermogravimetry was measured . we found that the higher thermal resistance and higher mechanical properties be possibly used insulation materials and for others industrial applications. | ||
