    Notes: Degradation resulting from weathering in low-density polyethylene (LDPE) films used in agricultural applications was investigated by a series of mechanical and spectroscopic characterization techniques. An easy, nondestructive, and comparatively sensitive test for measuring the durability of these films based on microhardness indentations is presented.

    Complexes of diorganotin(IV) dihalides with N, N′-dimethyl-2, 2′-bisimidazole (1993)

    Notes: Adducts of N, N′ -dimethyl-2, 2′-bisimidazole (DMBIm) with diethyl- and dibutyl-tin(IV) dihalides (Cl, Br) have been isolated and characterized. IR data for [SnR2X2(DMBIm)] compounds are in keeping with a six-coordinate tin atom with DMBIm acting as a bidentate ligand, whereas in [(SnR2X2)2(DMBIm)] the tin is five-coordinate and DMBIm acts as a bridging ligand. Measurements of conductivity in acetonitrile show the adducts to behave as non-ionogens in this solvent. NMR data show them to undergo dissociation in CDCl3.
