p-Benzoylacetamido styrene and p-(1-hydroxy-2-naphthoyl) amino styrene polymers are prepared by reacting polyaminostyrene with ethyl benzoylacetate or phenyl 1-hydroxy-2-naphthoate. Reference is made to reacting polyamino styrene with 5-pyrazolone acid halides also. Specifications 541,589 and 633,812 [both in Group XX], are referred to. |
