    摘要: Described herein are poly(aryl ether ketones) derived from biphenol which can be improved by incorporating bisphenol comonomers. The resulting polymers have lower melting points while the Tg is essentially unchanged resulting in good mechanical and crystallization properties.

    摘要: A phenolic allyl ether is provided which can be prepared by reacting a polyphenol with an allyl halide, said polyphenol described by the formula ##STR1## in which Ar is an aromatic moiety, L is a divalent cyclohexanenorbomane linking moiety, L' is a divalent cycloaliphatic moiety, Allyl is a phenolic allyl ether group, and each of m and n is a number within the range of 0 to about 10. Such phenolic allyl ethers include the reaction product of allyl halide with the product of the addition reaction of a phenol and a cyclohexenenorbornene compound such as 5-(3-cyelohexen-1-yl)bicyclo[2.2.1]hept-2-ene. The resulting phenolic allyl ether resins are useful as processing agents for polymaleimides.

    摘要: An improved olefin metathesis catalyst system is disclosed. The catalyst system comprises a transition metal halide metathesis catalyst and an organo transition metal hydride co-catalyst of the formulaL.sub.x --M--Hwherein M is a group IVB transition metal including zirconium, titanium or hafnium; L is a ligand selected independently from the group of hydrogen, halide and organic ligands such as an optionally substituted C.sub.1-20 alkyl or alkenyl, an optionally substituted C.sub.3-20 cycloalkyl or cycloalkenyl having 3 to 6 carbon atoms in the ring, an optionally substituted C.sub.5-20 cycloakadienyl having 5 carbon atoms in the cycloalkadienyl ring, or an optionally substituted C.sub.6-20 aryl or fused aryl, where at least one L is a cycloalkadienyl; and x is one less than the valence of M. The optional substitutions on the organic ligands include halogens, preferably chloride or flouride; C.sub.1-6 alkyl; C.sub.1-6 alkoxy; and C.sub.1-6 haloalkyl. The preferred ligand is a C.sub.5-20 cycloalkadienyl having 5 carbon atoms in the cycloalkadienyl group, e.g. cyclopentadienyl. The co-catalysts of this invention are combined with molybdenum or tungsten metathesis catalysts to provide an active catalytic system for the polymerization of cycloolefins, such as dicyclopentadiene.
