  • Patent number: 7423184
    Abstract: A method of making a carbonyl compound comprises contacting a compound comprising a secondary hydroxyl group with a basic metal oxide catalyst at a temperature sufficient to maintain the compound comprising a secondary hydroxyl group in a vapor phase.
    Type: Grant
    Filed: August 29, 2005
    Date of Patent: September 9, 2008
    Assignee: Sabic Innovative Plastics IP B.V.
    Inventors: Hugo Ingelbrecht, Arun Kumar, Ashok Ramakrishnan Menon, Pradeep Nadkarni, Rupesh Pawar
  • Publication number: 20080051522
    Abstract: A curable composition includes an olefinically unsaturated monomer and a poly(arylene ether) having two polymerizable groups and an intrinsic viscosity of about 0.05 to about 0.30 deciliters per gram. The composition exhibits an improved combination of high flow during molding and high post-cure stiffness and impact strength. The composition is particularly useful for fabricating plastic-packaged electronic devices.

  • Publication number: 20070093635
    Abstract: A poly(arylene ether) produced by combining a poly(arylene ether) solution with an antisolvent at a shear rate of greater than 50,000 sec?1. The high shear mixing conditions produce a poly(arylene ether) dispersion in which the poly(arylene ether) solid contains reduced amounts of undesirably fine particles.

  • Publication number: 20060229199
    Abstract: An alkylation method comprises reacting a hydroxy aromatic compound with an alkyl alcohol in the presence of an alkylation catalyst comprising a metal oxide wherein the alkylation catalyst, has a surface area to volume ratio of about 950 to about 4,000 m2/m3, an aspect ratio of about 0.7 to about 1.0 or a combination of the foregoing.

  • Publication number: 20060069229
    Abstract: A method for preparing a poly(arylene ether) with a reduced level of powder fines is described. In one embodiment, the method comprises oxidatively coupling a monohydric phenol in the presence of a solvent and a complex metal catalyst, to produce a poly(arylene ether) resin; and then removing a portion of the solvent to produce a concentrated solution having a cloud point Tcloud. The concentrated solution is then combined with an anti-solvent to precipitate the poly(arylene ether) in the form of a precipitation mixture. The concentrated solution usually has a temperature of at least about (Tcloud?10° C.) immediately before it is combined with the anti-solvent. The precipitation mixture has a temperature of at least about (Tcloud?40° C.) after its formation. Related poly(arylene ether) copolymers are also described.
