The interdependence between the curing conditions, structure, and the mechanical properties of tow neat phenolic resin systems was investigated. Changes of the distribution of the void diameters were characterized by light-an scanning electron microscope analyses. Tensile tests and dynamic mechanica

Starting from 6-amino-6-methylpentafulvene (2) ''ortho''-Cacylation or N-acylation can be achieved selectively. Treatment of 2 with phthaloyl-protected amino acid chlorides derived from alanine (3a) or valine (3b) leads exclusively to the formation of the ''ortho''-C-acylated derivatives 4, isolated
A novel method has been developed to toughen phenolic resin using phenoxy resin. Phenoxy resin was dissolved in phenol to form a glutinous mixture at 110ЊC, and an acid catalyst ( p-toluene sulfonic acid, PTSA) was utilized to reduce the viscosity of mixture. The mixture was blended with resole-type
The chemical ionization mass spectra of eight monoterpene alkaloids from the gentianine group and their derivatives were investigated. Isobutane, methanol, ammonia, methylamine, ethylenediamine, diethylamine and triethylamine were used as reactant gases. The application of this technique for investi
## Abstract An __in situ__ semibatch polymerization process for making phenolic resin/montmorillonite clay nanocomposites is developed. It is found that auxiliary mixing in phenol allows intercalation of the monomer and polymer between montmorillonite clay layers. At 2.7% clay by mass the montmoril
