Abstract

NEW MATERIAL:An organic phosphorus compound of formula I (R4, R5, R6 and R7 are Hs, 1W18C alkyls, alkenyls, cycloalkyls, etc.; A is polyhydric alcohol residue, polyhydric phenol residue, etc.; m and n are integers 1W3, m+n is ≥2).
EXAMPLE: The compound of formula II.
USE: A stabilized resin component having improved heat and weather resistance for a flame-retardant resin or a resin containing a halogen, particularly a resin containing vinyl chloride.
PROCESS: A compound of formula III (R1 and R2 are the same as R4, R5, R6 and R7; R3 is phenyl or 1W4C alkyl-substituted aryl) is reacted with a polyhydric alcohol or polyhydric phenol in the presence of a catalyst, e.g. a hydroxide such as KOH, NaOH or CaOH of an alkali metal and an alkaline earth metal, an alcoholate or a carbonate thereof alone or in combination, under ordinary or reduced pressure to give the titled compound of formula I.
