A hot melt adhesive tie layer polymer blend for firmly adhering polyethylene to fluropolymers is disclosed.

Bonding method employing tie layers for adhering polyethylene to

Vinylidene fluoride polymer ultrafiltration membranes are prepared by casting a sheet of said polymer dissolved in a mixture of a specified solvent and a specified non-solvent, on a smooth substrate, evaporating a portion of the solvent from the sheet, immersing said sheet in a gelation liquid therefore, and optionally, stabilizing the gelled sheet by heat treatment thereof. A porous vinylidene fluoride polymer membrane having smooth, unwrinkled surfaces can be prepared in accordance with the above described process without restraining the membrane during the evaporation and gelation steps by utilizing triethyl phosphate as the solvent.

Porous vinylidene fluoride polymer membrane and process for its

Low shrinkage, mechanically strong, acid stable, carbon fiber reinforced poly(vinylidene fluoride) resin compositions are prepared by extrusion blending carbon fibers, which have been precoated with poly(vinylidene fluoride), with a poly(vinylidene fluoride) resin.

Coated carbon fiber reinforced poly(vinylidene fluoride)

Vinylidene fluoride polymer resin dispersed in carbon tetrachloride is chlorinated at elevated temperature in the presence of a specified initiator compound and triethanolamine and with exposure to ultraviolet light.

Chlorination of poly (vinylidene fluoride) using U-V radiation

A tough, flexible, nonelastic, high-modulus terpolymer composed of copolymerized units, in mole percents, of 45 to 55% ethylene, 40 to 50% tetrafluoroethylene and 3 to 9% hexafluoropropylene.
