AMINOPHOSPHINATE POLYMERS

摘要

The present invention provides an aminophosphinate mid functional co-polymer, or oligomer thereof, a method for its manufacture and a number of applications for it. The aminophosphinate co-polymer is of the formula (I): (A)<SUB>a</SUB>-[PO(OX)CR'<SUB>2</SUB>NR(R''NR)<SUB>m</SUB>CR'<SUB>2</SUB>-]<SUB>n</SUB>PO(OX)-(A)<SUB>b</SUB>; wherein: X is hydrogen or any suitable cation; each of the R groups, which may be the same or different, and each of the R' groups, which may be the same or different, is hydrogen, an optionally substituted alkyl, cycloalkyl, alkenyl, aryl, aralkyl, alkaryl or alkoxyalkyl group of 1-20 carbon atoms each of which may be optionally substituted once or more than once, R'' is an alkane group, substituted alkane group or heterocyclic group; and wherein A is derived from any suitable monomer, a and b are the same and each is an integer from 1 to 1000 or a and b are different and one is zero or an integer from 1 to 1000 and the other is an integer from 1 to 1000, m is zero or from 1 to 100, and n is zero or from 1 to 100.
