Abstract
NEW MATERIAL:The compound of formula I (A is 1W500C n-valent organic group; R is H, 1W5C lower alkyl, halogen, or alkoxy; m is integer 1W4; n is ≥1).
EXAMPLE: The diisocyanate of formula II.
USE: A raw material of various resins such as polyurethane, etc.
PROCESS: The polyisocyanate compound of formula I containing a carbonate bond is prepared by reacting the substituted-phenylene isocyanate haloformate of formula III (X is halogen) (e.g. p-isocyanatophenyl chloroformate) with the polyhydroxy compound of formula A-(OH)n (e.g. hydroquinone) in a solvent such as tetrahydrofuran, if necessary in the presence of a base such as triethylamine, etc.
