## Abstract Diacetylenes (DAs) having a dipolar Dβ__Ο__βA structure (D=donor: amino group; __Ο__=__Ο__βconjugation core; A=acceptor: pyridinium (Py) and bipyridinium (BPy) groups), __i.e.__, **4** (APBPyDA) and **5** (APPyPyDA), or an Aβ__Ο__βA structure, __i.e.__, **7** (DBPyDA) and **8** (PyDA(Cl
non-cross-linked and cross-linked, hydrophobically modified homo-and copolymers were synthesized by free-radical cyclo(co)polymerization of alkylmethyldiallylammonium chloride monomers in aqueous solution using ammonium persulfate as the initiator. Cross-linking was brought about by addition of a sm
Three disubstituted acetylenes with an adamantyl group-1-(p-adamantylphenyl)-2-chloroacetylene (ClpAdPA), 1-(p-adamantylphenyl)-1-propyne (pAdPP), and 1-(p-adamantylphenyl)-2-phenylacetylene (pAdDPA)-polymerized in good yields in the presence of MoCl 5 -or TaCl 5 -based catalysts. The highest weight
## SYNOPSIS 3,5-Dinitrobenzoyl chloride reacted with various alcohols such as phenol, biphenyl-4-01,lnaphthol, or diphenylmethanol to afford the 3,5-dinitrobenzoic acid ester derivatives which were catalytically hydrogenated to the corresponding diamines. The latter reacted with terephthaloyl dich
