Patent number: 5270411Abstract: A process for making a biodegradable aliphatic polyester and the polyester so formed is disclosed. The process comprises copolymerizing a cyclic ketene acetal having the structural formula ##STR1## where R is a bivalent moiety, and an olefin. This copolymerization occurs in a solution of a tertiary alcohol and in the presence of a free radical initiating effective amount of a compound having the structural formula ##STR2## where R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 are the same or different and are C.sub.1 -C.sub.20 hydrocarbyl, C.sub.1 -C.sub.20 hydrocarbyloxy, cyano, halogen, carboxy, carboalkoxy, carbonyl or formyl. The copolymerization occurs at a temperature in the range of between in excess of ambient temperature and less than 100.degree. C. and at a pressure in excess of about 2,000 psi.Type: GrantFiled: April 9, 1992Date of Patent: December 14, 1993Assignee: Quantum Chemical CorporationInventors: Biau-Hung Chang, Thomas S. Brima

Patent number: 5219930Abstract: Processes for converting vinyl alcohol polymers to poly(keto-esters) and the novel products obtained therefrom are disclosed. The process involves reacting a vinyl alcohol polymer, such as PVA or EVOH, with an organic peroxyacid oxidizing agent in an inert liquid medium at a temperature from -20.degree. C. to 150.degree. C. to convert the secondary hydroxyl groups of the vinyl alcohol polymer to carbonyl and oxycarbonyl groups. In another aspect of the invention, the vinyl alcohol copolymer is first reacted with an oxidizing agent capable of converting the secondary hydroxyl groups to carbonyl but not to oxycarbonyl and then subsequently oxidized using a peroxyacid to form oxycarbonyl. The poly(keto-esters) comprised of carbonyl units, oxycarbonyl units, hydroxyl-containing units and units which are primarily hydrocarbons in nature are photodegradable and biodegradable.Type: GrantFiled: January 21, 1993Date of Patent: June 15, 1993Assignee: Quantum Chemical CorporationInventors: Biau-Hung Chang, Jack Kwiatek, Thomas S. Brima

Patent number: 4980513Abstract: A process for making a hydrocarbyl vinyl ketone is disclosed. In this process a ketone having the structural formula CH.sub.3 COR, where R is lower alkyl, phenyl or C.sub.7 -C.sub.8 aralkyl, is reacted with methanol in an oxygen-containing atmosphere in the presence of a catalyst system comprising a catalytically effective amount of iron on an inert support. In another preferred embodiment, the catalyst system comprises a catalytically effective amount of a precious metal selected from the group consisting of silver and gold, in addition to iron, supported on an inert material.Type: GrantFiled: January 4, 1990Date of Patent: December 25, 1990Assignee: Quantum Chemical CorporationInventors: Thomas S.

Patent number: 4767574Abstract: A method is disclosed for the production of esters by reaction of an allylic ether with carbon monoxide in the presence of a catalytically effective amount of a Group VIII noble metal catalyst and a halide compound to obtain esters. The halide compound is present in an amount sufficient to prevent the catalyst from being converted into a Group VIII metal during the reaction. When the reaction is conducted in the presence of a quaternary ammonium salt the ester may be extracted by solvent extraction to minimize catalyst decomposition caused when extractive distillation is used to separate the ester.Type: GrantFiled: October 3, 1985Date of Patent: August 30, 1988Assignee: National Distillers and Chemical CorporationInventors: Ronnie M. Hanes, Thomas S. Brima
