Crosslinkable epoxy thermoplastic with preparation

The crosslinkable epoxy thermoplastic modified with 5 wt % grafted rubber concentrate (CET-GRC) was prepared according to published procedure (5). The rubber domains are nominally 0.1 micron in diameter and consist of a core-shell structure with a 0.03 micron diameter polystyrene seed. Blocks of the CET-GRC were cryo-polished at -90°C using a diamond knife to provide a smooth face for SPM imaging. Some of these surfaces were post stained in OSO4 vapors by suspending the polished blocks in sealed containers over an aqueous solution of... 

More recently, a number of interstitially crosslinked coating materials have been prepared.These are blends in which a water-soluble or water-dispersible resin, capable of crosslinking, is blended with an ordinary thermoplastic emulsion. The main resins include aminoplast, phenol-formaldehyde, polyurethane, epoxy, and drying oils. Applications include sealants, adhesives, and architectural coatings.
