Abstract: This invention relates to vinyl ether-based coatings for which properties such as color stability, thermal stability, mechanical stability, hydrolytic stability, and resistance to embrittlement may be maintained and properties hydrogen generation and blocking are minimized.

Abstract: This invention relates to vinyl ether-based coatings for which properties such as color stability, thermal stability, mechanical stability, hydrolyric stability, and resistance to embrittlement may be maintained and properties hydrogen generation and blocking are minimized. The invention also relates to stabilizers which control these properties in the coatings.

Abstract: Polymer precursor formulations suitable for stereolithography may be prepared from compositions containing vinyl ether functionalized compounds and epoxy functionalized compounds plus an effective amount of a cationic photoinitiator.

Abstract: A radiation curable coating composition comprising acrylate oligomers and monomers, vinyl ether monomers, and a free radical photoinitiator. The vinyl ether monomers replace N-vinyl-pyrrolidone or other undesirable reactive diluents while retaining or modifying the properties of coatings using such diluents.

Abstract: Vinyl ether terminated ester oligomers having a range of molecular weights are prepared by reacting a vinyl ether terminated polybasic ester with a polyol in the presence of a catalyst. Continual removal of a hydroxy monovinyl ether avoids formation compounds containing acetal moieties. Alternatively, a polybasic ester is chain extended with a polyol with continual removal of the alcohol by-product. Then, the terminal ester moieties are end capped with a monohydroxy vinyl ether. The oligomers have application in coatings and the like.

Abstract: Novel thermoplastic sheet materials, absorbant articles formed therewith and method of producing such sheet materials are disclosed. The novel thermoplastic sheet materials are soft and pliable having a high modulus, high impact resistance and tear strengths and enhanced tape adhesion. The novel thermoplastic sheet materials are formed directly during a coextrusion process which may thereafter include an embossing step. The novel, coextruded thermoplastic sheet materials comprise a plurality of coextruded layers having high modulus outer layers for permitting pressure-sensitive adhesive tape-tab fasteners to be positioned and repositioned thereon without losing substantial tape adhesion therebetween or tearing the sheet materials following their original attachments.

Abstract: A vinyl ether oligomer especially useful for coatings is prepared by reacting an hydroxyl-terminated polyester, a diisocyanate, and a hydroxy monovinyl ether having formulas as defined herein.

Abstract: An article is coated with alternate microscopically thin layers of titanium nitride and gold alloy using a cathodic sputtering process to provide a microlaminated coating having the color and brilliance of a much thicker coating of the gold alloy while being more resistant to corrosion and scratching.

Abstract: A conveyor installation comprises a framework having stationary guides with plastic contact surfaces. A conveyor belt is mounted for travel on the framework and includes plastic carriers mounted on plastic chain links. The carriers are supported for sliding contact with some of the guides which define vertical support rails. The carriers are connected to the links by upstanding coupling members. Plastic clip-on sleeves are mounted on the coupling members for engagement with some of the stationary guides to minimize wear of the chain, while assuring a low friction sliding contact between the chain and the guides. Snap-on pan guides are insertable into recesses of the carriers.
