  • Patent number: 4919808
    Abstract: Semipermeable membranes which may be used in a variety of separation processes such as desalination, sugar separation, etc. are prepared by contacting a porous support backing material such as polysulfone with an aqueous solution of a hydrazine compound. The coated support material is then contacted with an organic solution of an aromatic polycarboxylic acid chloride whereby an interfacial polymerized condensation reaction product is formed on the surface of the support. The thus formed composite is then cured at an elevated temperature and recovered.

  • Patent number: 4908096
    Abstract: Ethers of oligomeric phenol-dialdehyde condensation products containing vinyl benzyl moieties in at least half of the ether moieties are excellent photosensitive prepolymers. Through simple masking and irradiation with a broad range of radiation types, such a resin as a coating can be selectively patterned by dissolving the non-irradiated and non-photocrosslinked portions of the prepolymer with a large variety of common solvents. The outstanding differential solubility between the photocrosslinked and non-crosslinked regions of the prepolymer allows excellent resolution with good edge sharpness. Subsequent thermal curing affords a void-free infusible glassy solid with minimum shrinkage, excellent planarity characteristics, and high resistance to cracking.

  • Patent number: 4900794
    Abstract: Thermosetting resins which are essentially vinylbenzyl end-capped ethers of the oligomeric condensation products of certain dihydric phenols and formaldehyde are readily polymerized to give an extensively cross-linked polymer particularly useful in printed circuit boards and similar laminates. Effective cost reduction may be enjoyed by replacing up to 50% of the vinylbenzyl moieties by other groups, such as alkyl and benzyl groups, without destroying the usefulness of the resulting thermosetting resins. The vinylbenzyl ether product from bisphenol-A is especially recommended.

  • Patent number: 4885091
    Abstract: Chlorine-resistant semipermeable membranes which comprise an interfacial polymerized reaction product composited on a porous support backing material may be prepared by contacting a porous support material such as polysulfone with an aqueous solution of an aromatic polyamine containing a chlorine substituent on the aromatic ring such as 5-chlor-m-phenylenediamine. The coated support material is then contacted with an organic solvent solution of aromatic polycarboxylic acid chloride such as trimesoyl chloride for a period of time sufficient to form an interfacial polymerized reaction product on the surface of the support material. The resultant semipermeable membrane is then cured at curing conditions to form the desired composite. The resultant membrane composite may be used in separation processes such as desalination of brackish or sea water, the membrane being resistant to attack by chlorine which is present in the water.

  • Patent number: 4824920
    Abstract: The resins resulting from converting dicyclopentadiene-phenol adducts to their corresponding vinylbenzyl ethers are an excellent matrix in which to embed fibers to produce a composite. Such resins, especially as a blend of materials with varying molecular weight distribution, are amorphous materials whose glass transition temperature is well under the curing temperature, and whose solubility permits solutions with high solids content so as to afford coatings with high resin content. The extensively crosslinked polymer resulting from therma, photochemical, or free radical initiated polymerization has excellent thermal and electrical properties for use in multilayer circuit boards.

  • Patent number: 4792404
    Abstract: Saline water containing a chlorine-containing compound in the form of free chlorine, hypochlorite, etc. which has been added as a disinfectant or antibacterial compound is desalinated by passing the saline water through a semipermeable membrane which is resistant to the chlorine. The saline water is passed through this membrane at a temperature in the range of from ambient to about 50.degree. C. and a pressure in the range of from about 1380 to about 6895 kPA (200-1000 psi). The chlorine-resistant semipermeable membrane comprises an interfacial polymerized condensation reaction product composited on a porous backing support material which has been prepared by contacting a porous support material such as polysulfone with a solution of a diaryl methylene monomer containing at least one amine radical on each aryl nucleus.
