Patent number: 5152939Abstract: A method for forming carbon-carbon composites consists of impregnating structures with carbon-forming precursor compounds comprising multi-functional benzoxazine compounds. The impregnated structures are pyrolyzed to form carbonaceous char which serves to fill the interstices in the structure, thus densifying the composites. The process of impregnation and pyrolysis is repeated as many times as required to obtain the composite density desired. Unusually high char yields are produced by multi-functional benzoxazine compounds in which benzoxazine are joined to each other through a bridge characterized by having conjugated unsaturation associated therewith. A number of preferred compounds providing unexpectedly high yields of char are shown, enabling the desired densification to be achieved with a minimum number of impregnation and pyrolysis cycles, thereby reducing the costs of forming the composites.Type: GrantFiled: March 12, 1991Date of Patent: October 6, 1992Assignee: Edison Polymer Innovation Corp.Inventor: Hatsuo Ishida

A resin or elastomer which is not reactive with the polyisocyanate may be added as a third component to impart flexibility or other desirable properties to the magnetic layer of tape.Type: GrantFiled: February 7, 1979Date of Patent: March 17, 1981Assignee: Victor Company of Japan, Ltd.Inventors: Tunehide Naruse, Ikuo Matsumoto

Patent number: 4255535Abstract: There are provided composites having near-zero uniaxial thermal expansion coefficients. One or more polyacetylenes having a negative uniaxial thermal expansion coefficient are uniaxially or biaxially oriented within one or more solid matrix materials having a positive thermal expansion coefficient to yield a composite material having a uniaxial thermal expansion coefficient which is nearly zero. The polyacetylenes are obtained by the solid-state polymerization of crystals of monomers containing at least one --C.tbd.C--C.tbd.C-- grouping per molecule. Also provided are processes for producing the above-described composites.Type: GrantFiled: December 15, 1978Date of Patent: March 10, 1981Assignee: Allied Chemical CorporationInventors: Ray H. Baughman, Edith A. Turi, Anthony F. Preziosi, Kwok-Chun Yee

Patent number: 4248979Abstract: According to our invention, thermoplastic poly(vinyl chloride) block copolymer resins of the (AB).sub.n type are formed which are flexible without the addition of an external plasticizer for poly(vinyl chloride). These novel block copolymer resins have average molecular weights (Mn) in the range of from about 15,000 to 60,000 and contain alternating rigid poly(vinyl chloride) segments and flexible linear aliphatic polyether or polyester segments, each having an average molecular weight in the range of from about 1,000 to 5,000. The resins of our invention have excellent physical properties which make them suitable substitutes for externally plasticized poly(vinyl chloride) homopolymers, particularly in automotive applications.Type: GrantFiled: February 17, 1978Date of Patent: February 3, 1981Assignee: General Motors CorporationInventors: John J. Laverty, Zachariah G. Gardlund

Patent number: 4224217Abstract: The char-forming characteristics of aromatic polymers containing one or more combustion resistant components are improved by incorporating therein a polybenzyl, a polyallyl, or an allyl/benzyl moiety. As an example, a styrene polymer comprising a halogenated comonomer such as bromostyrene is rendered char-forming by the presence of copolymerized vinylbenzyl chloride in the styrene polymer. Such polymeric compositions are useful in the manufacture of shaped articles such as housings for electrical appliances.Type: GrantFiled: January 5, 1978Date of Patent: September 23, 1980Assignee: The Dow Chemical CompanyInventors: Kent S. Dennis, Joseph W. Raksis

Patent number: 4206102Abstract: Abrasion resistant polyurethane elastomers using a combination of a waxing agent, a powdered mineral type lubricant and a polyhalogenated polyalkylene powder are disclosed. Although all three types are known to impart abrasion resistance to polyurethane elastomers, a synergistic effect has been found in the use of these additives such that better abrasion resistance is found with smaller quantities of additives.Type: GrantFiled: September 15, 1976Date of Patent: June 3, 1980Assignee: Mobay Chemical CorporationInventors: J. W. Britain, George J. Schexnayder
