“…10 Optimum conditions were found for the preparation of 2,6-dimethylphenyl acrylate, 2,4,6-trichloro-, 2,4,6-tribromo-, 2,4,6-trimethyl-, 2,6-diisopropyl-and 2,6-di(tert-butyl)-phenyl methacrylates, 2,4,5-trichlorophenyl acrylate 21 and methacrylate. 22 PMA with substituents in the aromatic ring containing the aldehyde and ketone, 23 carboxy, 24,25 benzyl, 26 tetracyanocyclobutyl 27 and dioxolane 28 groups have been described. Special mention should be made of (meth)acrylates of hydroxyphenylacetic 29 and hydroxybenzoic 24,25 acids as well as of surfactant salts 30 of the general formula CH 2 =CMeC(O)OC 6 H 4 (CH 2 ) n X [n = 3, 7; X = CO 2 Na, N + (C n H 2n+1 ) 3 Z 7 ; Z = Cl, Br, I, MeSO 4 ].…”

We extend our previous formulation of low-energy QCD in terms of an effective lagrangean containing operators of dimensionality d ≤ 6 constructed with pseudoscalars and quark fields, describing physics below the scale of chiral symmetry breaking. We include in this paper the vector and axial-vector channels. We follow closely the Extended Chiral Quark Model approach and consistently work in the large-N c and leading log approximation and take into account the constraints from chiral symmetry and chiral symmetry restoration. The optimal fit of all parameters gives further support to a heavy scalar meson with a mass ∼ 1 GeV and a value of the axial pion-quark coupling constant g A 0.55 to 0.66, depending on some assumptions concerning the Weinberg sum rules.
