    Associative organotin polymers. I. Symmetric trialkyltin fluorides: Synthesis and properties (1989)
    Bognor Regis [u.a.] : Wiley-Blackwell

    Notes: Four novel symmetric tri-n-alkyltin fluorides were prepared. In this homologous series, melting point decreases with increase in the carbon chain length while an x-ray diffraction study shows an increase in amorphousness. 1H-NMR spectra in cyclohexane, a nonpolar solvent in which these compounds form long polymeric chain, show a peak broadening effect due to high solution viscosity at very low solute concentration. Contrary to this, the spectra in CDCl3, a polar solvent in which these compounds are monomeric, show well resolved and narrow peaks. IR frequencies for Sn—C vibrations have been assigned.

    Mechanical relaxation of flame retardant polycarbonate using the cole-cole method (1985)
    Stamford, Conn. [u.a.] : Wiley-Blackwell
    Polymer Engineering and Science 25 (1985), S. 105-112 
    Details
    ISSN: 0032-3888

    Notes: The frequency dependence of the complex-shear modulus of a nonbrominated flame-retardant polycarbonate has been successfully represented from 1 hertz (hz) to 1 gigahertz (ghz) at 190°C using a mechanical analog of the Cole-Cole dielectric analysis. Two sets of retardation times were required centered about 74 msec and 16 μsec. The β value for the short time response was 0.83 and for the longer time response was 0.58. The values of JoN determined from the common point at which the terminal-zone arc and the transition-zone arc touch the Jc″ = 0 axis yields an entanglement molecular weight, Me, of 1470 g/mole.

    Assortative mating for IQ and personality due to propinquity and personal preference (1988)
    Springer
    Behavior genetics 18 (1988), S. 339-345 
    Details
    ISSN: 1573-3297
    Keywords: assortative mating ; IQ ; Eysenck's Personality Inventory (EPI) ; extraversion ; neuroticism
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Psychology
    Notes: Abstract The role of personal preference as an active process in mate selection is contrasted with the more passive results of limitations of available mates due to social, educational, and geographical propinquity. The role of personal preference estimated after removing the effects of variables representing propinquity was still significant for IQ and Eysenck's extraversion-introversion and inconsistency (lie) scales, even though small.

    Time temperature dependence of dual coated lightguide pullout measurements (1989)
    Stamford, Conn. [u.a.] : Wiley-Blackwell
    Polymer Engineering and Science 29 (1989), S. 1169-1171

    Notes: The strength of the bond between primary coating and glass for a dual coated lightguide may be judged by fixing the coating to a substrate and pulling the glass out. The values obtained from such measurements are shown to exhibit a temperature and rate dependence similar to the mechanical properties of the primary coating for a given coating system. Here we combined temperature and rate data for a universal description of the coating to glass adhesion for a dual coating system.

    The effects of cure temperature on the thermomechanical properties of UV curable coatings (1989)
    Stamford, Conn. [u.a.] : Wiley-Blackwell
    Polymer Engineering and Science 29 (1989), S. 1165-1168

    Notes: A method is presented to study the mechanical behavior of soft, UV curable coating material as a function of temperature of the prepolymer at cure. For such materials, the crosslink density (hence, equilibrium modulus) is found to decrease with increasing cure temperature. The three primary coatings are: a polyurethane acrylate with a nominal equilibrium tensile modulus of 200 psi, a polyurethane acrylate with a nominal equilibrium modulus of 1200 psi, and a non-urethane acrylate with a nominal equilibrium tensile modulus of 60 psi.
