    Antioxidant-associated color problems in vinyl foams (1974)
    Stamford, Conn. [u.a.] : Wiley-Blackwell

    Notes: Investigations of chemically-blown vinyl foam systems, based on electrical grade plasticizers, have shown that the inclusion of 2,2′-bis (4-hydroxyphenyl) propane (BPA) as an antioxidant results in color formation in the finished foam. Color formation appears to be due to interactions between BPA and the azodicarbonamide blowing agent. Metal ion(s) present in vinyl stabilizer/kickers are also shown to have an effect on color hue though not on color development per se. Mechanisms for the development of quinoidal and diazo color bodies, based on the reaction of BPA and azodicarbonamide are postulated. Based on these reaction mechanisms, it is shown that it is possible to choose an antioxidant that will not interact with azodicarbonamide. A rudimentary screening procedure is described for evaluating these systems.

    In vivo histologic and biomechanical characterization of a biodegradable particulate composite bone cement (1989)
    Hoboken, NJ : Wiley-Blackwell
    Journal of Biomedical Materials Research 23 (1989), S. 1-16 
    Details
    ISSN: 0021-9304
    Keywords: Chemistry ; Polymer and Materials Science

    Topics: Medicine , Technology
    Notes: A biodegradable particulate composite bone cement consisting of a crosslinked gelatin matrix and tricalcium phosphate particles was implanted intraosseously in rabbits for up to 12 weeks. Cured cylindrical implants were inserted in holes drilled in the proximal tibial metaphysis. Sequential fluorochrome labeling and radiographs were done, and specimens were processed for decalcified and nondecalcified histology. At 4 weeks, the cross-sectional diameter of the implant was slightly greater than at implantation. There was considerable dissolution of the matrix and some new bone ingrowth. At 12 weeks, the diameter was reduced to half the original diameter and bone had grown throughout the matrix. In the distal femur, freshly mixed cement was used to stabilize an osteochondral fracture. Mechanical testing of the cement-stabilized fracture revealed a decrease in compressive strength and modulus at 4 weeks followed by an increase to greater than initial values at 12 weeks. Over time, the osteochondral fragment subsided into the underlying cement, but the subsidence did not correlate with mechanical strength. This osteochondral fracture model permits measurement of the overall material properties of a cement simultaneously weakened by resorption and reinforced by ingrowing bone.

    The effect of blending resins on plastisol performance (1980)
    Brookfield, Conn. : Wiley-Blackwell

    Notes: Blending resins are well known by plastisol compounders as an economical substitute for PVC dispersion resin and as viscosity modifier. As dispersion resin supply tightens, interest grows in blending resins and how to choose the one that best fits the compounder's specifications. Eleven representative blending resins have been characterized, compounded into plastisols and screened for performance. A regression analysis and resulting contour plots have supplied a means of correlating resin molecular weight, particle size and surface area with plastisol, gel/fusion, and physical properties. The trends described in the contour plots allow the prediction of the best blending resin criteria for a specific application.

    A monomeric plasticizer for high temperature applications (1986)
    Brookfield, Conn. : Wiley-Blackwell

    Notes: The results of this study demonstrate that high molecular weight and predominantly linear diundecyl phthalate (DUP) provide improved performance properties and cost savings when used as a partial or total replacement for trimellitate plasticizers in critical applications such as vinyl electrical insulations and crashpad covers. DUP is shown to be a permanent and stable plasticizer with a high efficiency in improving low-temperature flexibility of formulated vinyls.
