Abstract
Disclosed are processes for preparing a process for preparing a modified polyphenylene ether which comprises reacting any one of a borane compound having at least one boronhydrogen bond, an .alpha.,.beta.-unsaturated carbonyl compound or a mercaptane having a carbonyl group, a hydroxyl group or an alkoxysilyl group with a polyphenylene ether having a carbon-carbon unsaturated bond in a substituent, and optionally oxidizing the resulting borane-modified PPE under alkaline conditions.
Claims5
A process for preparing a carbonyl group-modified polyphenylene ether which comprises reacting a mercaptan having a carbonyl group and represented by the formula:
- (HS).sub.m --R.sup.3 --(COR.sup.4).sub.n
- wherein m and n each represent an integer of 1 to 4, R.sup.3 represents a divalent to hexavalent saturated aliphatic hydrocarbon group having one to 29 carbon atoms or an aromatic hydrocarbon group, and R.sup.4 represents an alkali metal oxy group, a hydroxyl group, an aryloxy group, an alkyloxy group or a hydrocarbonoxy group, with a polyphenylene ether having a carbon-carbon unsaturated bond in a substituent.
