KETONIC AND NON-KETONIC ESTROGENS

Annals of Internal Medicine, 1937
Excerpt INTRODUCTION Active experimental work on the internal secretion of the ovary began with the demonstration of Knauer1in 1899 that transplantation of the ovary from its normal site did not pr...

Synthesis and properties of novel copolymers of poly(ether ketone diphenyl ketone ether ketone ketone) and poly(ether amide ether amide ether ketone ketone)

Polymer Engineering & Science, 2013
New monomers, 4,4′‐bis(4‐phenoxybenzoyl)diphenyl (BPOBDP) and N,N′‐bis(4‐phenoxybenzoyl)−4,4′‐diaminodiphenyl ether (BPBDAE), were conveniently synthesized via simple synthetic procedures from readily available materials. Novel copolymers of poly(ether ketone diphenyl ketone ether ketone ketone) (PEKDKEKK) and poly(ether amide ether amide ether ketone ...

Structural study on poly(ether ether ketone ketone)‐poly(ether biphenyl ether ketone ketone) copolymers

Macromolecular Rapid Communications, 1996
AbstractStructures of poly(ether ether ketone ketone)‐poly(ether biphenyl ether ketone ketone) copolymers were studied by using small angle X‐ray scattering and the one‐dimensional electron density correlation function method. The results revealed that structures of the aggregated state of the copolymers depend closely on the biphenyl content (nb ...

Synthesis of copolymers of poly(ether sulfone ether ketone ketone) and poly(ether ketone diphenyl ketone ether ketone ketone) by electrophilic Friedel–Crafts solution polycondensation

Polymers for Advanced Technologies, 2011
AbstractA new monomer, 4,4′‐bis(4‐phenoxybenzoyl)diphenyl(BPOBDP), was synthesized via a two‐step synthetic procedure. A series of novel poly(ether sulfone ether ketone ketone)/poly(ether ketone diphenyl ketone ether ketone ketone) copolymers were prepared by electrophilic Friedel–Crafts solution copolycondensation of isophthaloyl chloride (IPC) with a
