US Patent:

20200199297, Jun 25, 2020
Filed:

Mar 27, 2018
Appl. No.:

16/497553
Inventors:

- Bergen op Zoom, NL
Huseyin Tas - Delmar NY, US
Mark R. Denniston - Alfamont NY, US
International Classification:

C08G 65/44
C08G 65/40
C08L 71/12
Abstract:

A poly(phenylene ether) copolymer of 2-methyl-6-phenylphenol and a dihydric phenol having an absolute number average molecular weight of 1,000 to 10,000 grams/mole is made by polymerization of 2-methyl-6-phenylphenol and a dihydric phenol in the presence of molecular oxygen, a polymerization catalyst comprising a metal ion and at least one amine ligand, and a solvent composed of at least 95 weight percent of a C-Calcohol selected from methanol, ethanol, 1-propanol, and 2-propanol. The poly(phenylene ether) copolymer can be, for example, a copolymer of 2-methyl-6-phenylphenol, 2,2-bis(3,5-dimethyl-4-hydroxyphenol)propane, and optionally 2,6-dimethylphenol. The poly(phenylene ether) copolymer finds utility in curable compositions, cured compositions, and articles.

US Patent:

20200172729, Jun 4, 2020
Filed:

Mar 27, 2018
Appl. No.:

16/497547
Inventors:

- Bergen op Zoom, NL
Huseyin Tas - Delmar NY, US
International Classification:

C08L 71/12
C08G 65/40
Abstract:

A solution of a poly(phenylene ether) copolymer derived from 2-methyl-6-phenylphenol and a dihydric phenol in a non-halogenated solvent is useful in curable compositions. The copolymer has less than 0.5 weight percent monohydric phenols having identical substituents in the 2- and 6-positions of the phenolic ring, and an absolute number average molecular weight of 1,000 to 10,000 grams/mole. A solution of a poly(phenylene ether) copolymer derived from 2-methyl-6-phenylphenol, 2,6-dimethylphenol, and a dihydric phenol in a non-halogenated solvent is also useful in curable compositions. This copolymer has an absolute number average molecular weight of 1,000 to 5,000 grams/mole. A cured composition is obtained by heating curable compositions composed of the poly(phenylene ether) copolymer solutions and thermoset resins for a time and temperature sufficient to evaporate the non-halogenated solvent and effect curing. The compositions can be used for preparation of composites for printed circuit boards.

Appl. No.:

16/377935
Inventors:

- Bergen op Zoom, NL
Huseyin Tas - Delmar NY, US
International Classification:

C08G 81/02
C08G 65/40
C07C 39/17
Abstract:

A phenylene ether oligomer has repeating units of the structureand less than 30 weight percent of repeating units derived from a monohydric phenol having identical substituents in the 2- and 6-positions, wherein the phenylene ether oligomer includes a vinyl benzene ether end group, an amine end group, maleimide end group, a norbornene end group, an anhydride end group, or a combination comprising at least one of the foregoing. The phenylene ether oligomer can be used to provide a curable composition. The curable composition can be cured to provide a thermoset composition. Articles comprising the thermoset composition are also described.
