  2,5-Dihydro-1H-1,2,4-triazol-2-yl radicals: Syntheses and properties

  摘要：

  A range of 2,5-dihydro-1H-1,2,4-triazol-2-yl radicals 2b-p has been prepared by dehydrogenation of the corresponding 4,5-dihydro-1H-1,2,4-triazoles 5b-p which have been synthesized using various methods. EPR, ENDOR and NMR studies have led to a complete analysis and full assignment of all hyperfine coupling constants. The pi-SOMO, having a node at the C(3) methine carbon, is mainly confined to the nitrogens of the five-membered ring, particularly to those of the hydrazyl moiety.

  The invention relates to a heat-activable pressure-sensitive adhesive. Provision is made for this heat-activable pressure-sensitive adhesive to comprise a polymer or copolymer formed from a monomer composition comprising at least 50% by weight of a compound of the formula CH 2 ═CH(R 1 )(COOR 2 ), wherein R 1 represents H or CH 3 and R 2 represents H or an alkyl chain having 1 to 30 carbon atoms, the polymer or copolymer having a static glass transition temperature of −10° C. to 120° C.; a temperature activation range of 15° C. or less; and a molecular weight distribution M w /M n of 2.5 or less.
