Characterization of PF Resol/Isocyanate Hybrid Adhesives
Water-based resol phenol formaldehyde, PF, and organic polymeric methylenebis(phenylisocyanate), pMDI, are the two primary choices for the manufacture of exterior grade wood-based composites. This work addresses simple physical blends of pMDI dispersed in PF as a possible hybrid wood adhesive. Part …

The Interaction of a Mutant Gene, Paddlefoot (Pf), and a Teratogen, 6-Azauridine, on Limb Development in Two Inbred Strains of Mice.
It is well known that mutant genes and environmental agents acting alone will induce developmental malformations. Within the past twenty-five years, more attention has been given to the interaction of the whole genome and specific mutant genes with either chemical or physical teratogens. Results of …
