This research is moving toward the determination of experimental conditions necessary for the production of true silicone-epoxy copolymers. By using C-13, Si-29 and Al-27 NMR spectroscopy it was established that Al(acac)3 is a disproportionation catalyst for phenyl containing silanols.

Siebert and Riew (4) described the chemistry of the in situ particle formation. They proposed that the composition of the particle is a mixture of linear CTBN-epoxy copolymers and crosslinked epoxy resin. The polymer morphology of the CTBN toughened epoxy systems was investigated by Rowe (5) using transmission electron microscopy by carbon replication of fracture surfaces. Riew and Smith (6) supported the... 

Mild steel tanks are generally recommended, but for certain processes, Type 304 or 316 stainless steel may be desirable. For some services, mild steel tanks with solvent-resistance linings, such as phenolic-epoxy copolymers, may even be preferred.

Acrylic copolymer, modified bisphenol A-epichlorohydrin epoxy resin (3.9%), dipropylene glycol monobutyl ether (3.5%), propylene glycol ethyl ether (1.4%), 2-propoxyethanol (0.7%), ammonia (0.4%) Uses Acrylic-epoxy copolymer for general metal, industrial maintenance, and automotive metal coatings... 

Waterborne epoxy resin (99) has been used for lamination. The epoxy copolymers PD-6049 and PD-4070 are supplied by Celanese at 69% solids in glycol ether co-solvents, which can readily be dispersed with water. When the dispersion is formulated with an aminoplast catalyst,... 

The acrylic modified epoxy copolymer can be neutralized via the pendant carboxyl groups to provide a water-dispersible system with good hydrolytic stability. The grafting is presumed to occur onto the methylene hydrogens of the glycidyl group in the epoxy resin ... 

The search is always on for new, more cost effective alloys and, in Japan, Sumitomo Chemical and Yamagata University have developed a unique plastic alloy which is environmentally friendly, lower priced, has better heat resistance and better electrical properties than comparable products currently being marketed. The new alloy has been derived from the combination of polyphenylene (PPE) with an ethylene-epoxy copolymer. Furthermore, the compound s structure has been controlled to improve its processability. Possible uses include insulation films and housings of mobile phones and other electronic appliances. 

The best measure to prevent corrosion of an oil tank bottom is to apply a thin film of epoxy copolymer and coal tar epoxy coating. A drainage facility may be incorporated for minimizing the buildup of water at the tank bottom. At the exterior of the tank bottom, corrosion penetrating...
