Patent number: 7256250Abstract: The object of the present invention is a biodegradable polymer network and methods to make it. The polymer network consists of a cross-linked polyester resin, which is composed of hydroxy acid units, structural units derived from an unsaturated bifunctional monomer, and structural units derived from a polyol monomer. The polyester resin is produced directly by a polyoon-densation reaction, after which it is cross-linked to a polymer of high molecular weight The polyester can be co-polymerised with a co-monomer increasing flexibility, or be blended with a reactive macromonomer, which adds elasticity and crosslinking density. The prepared polymer network can be especially used to coat continuous or singular objects made of fibrous, porous, biomass based or inorganic materials, or as a blending component in these, or used to impregnate these in order to induce water durability, barrier properties, elasticity, coherence or mechanical strength.Type: GrantFiled: October 11, 2002Date of Patent: August 14, 2007Assignee: JVS-Polymers OyInventors: Jukka Tuominen, Janne Kylmä, Jukka Seppälä, Johan-Fredrik Selin

Patent number: 6559244Abstract: A processable poly(hydroxy acid) composition which has been stabilized by adding to the polymer during the melt processing stage 0.05-3% by weight of a peroxy compound the degradation of which produces one or more acid radicals, and which has good melt strength and elasticity. The melt strength is high enough to produce films with conventional methods as the film blowing method.Type: GrantFiled: October 16, 1995Date of Patent: May 6, 2003Assignee: Neste OyInventors: Anders Sodergard, Johan-Fredrik Selin, Maria Niemi, Carl-Johan Johansson, Kersin Meinander

Patent number: 6214967Abstract: A two-step process is described for the polymerization of lactide to polylactide, in which process in the first step polymerization is carried out to a conversion of at least 50% by weight, and in the latter step the polylactide is polymerized further to a high conversion in conditions in which the mixing of the melt and the evaporation of the lactide are avoided.Type: GrantFiled: October 13, 1999Date of Patent: April 10, 2001Assignee: Fortum Oil and Gas OyInventors: Kari Jansson, Jukka Koskinen, Johan-Fredrik Selin

Patent number: 6187901Abstract: The invention relates to a method for the removal of lactide from polylactide and recovery of lactide from a lactide-containing gas by cooling the hot lactide-containing gas, wherein a polymer melt traveling through a nozzle forms thin threads the surface area of which is so large that in a normal-pressure or vacuum evaporator the lactide evaporates from the polymer rapidly into a hot carrier-gas flow and the polymer settles under gravity onto a collecting device. A hot lactide-containing gas is cooled rapidly to a temperature below 100° C., whereupon the lactide crystallizes from gas, forming lactide crystals, which are separated from the gas.Type: GrantFiled: August 13, 1999Date of Patent: February 13, 2001Assignee: Fortum Oil and Gas OyInventors: Jukka Koskinen, Johan-Fredrik Selin, Nikitas Katsaras, Kari Kaariainen

Patent number: 5925726Abstract: The invention concerns a novel melt-processible copolyester and a process and prepolymer for the preparation thereof. The copolyester contains structural units derived from a polyester and structural units derived from diepoxy, and the polyester units at least essentially consist of hydroxy acid monomers. The bonds between the structural units are ester bonds and the number average molar mass, M.sub.n, is at least 10,000 g/mol, its weight average molar mass, M.sub.w, is over 20,000 g/mol and molar mass distribution, expressed as the ratio M.sub.w /M.sub.n, is over 2. The copolyester is hydrolytically degradable and it can be used as a biodegradable polymer for the manufacture of injection moulded articles as well as thermoformed and blow moulded packages, pouches, sacks and bottles, for the coating of sacks bags and films made from paper or cardboard and for the preparation of fibres, fibre cloths and expanded polymer articles.Type: GrantFiled: November 6, 1997Date of Patent: July 20, 1999Assignee: Neste OYInventors: Jukka Seppala, Mika Harkonen, Kari Hiltunen, Johan-Fredrik Selin, Jyrki Hakola

Patent number: 5380813Abstract: The present invention relates to a production method of lactic acid-based polyurethanes. In the first phase of the product ion, the monomeric lactic acid is polymerized into an oligomer, the molecular weight thereof being about 500 to 10,000. Next, the oligomer thus obtained is copolymerized with an isocyanate reacting with the free hydroxyl and carboxyl groups thereof into polyurethane with a high molecular weight. To make the oligomer react with diol prior to the copolymerization is unnecessary according to the invention. The lactic acid used need not be absolutely pure, and by modifying the process, various biodegradable end products can be obtained therefrom, which according to the invention are appropriate for the material of disposable packages, agricultural film or planting pots, or as a coating of fertilizer granules.Type: GrantFiled: October 15, 1993Date of Patent: January 10, 1995Assignee: Neste OYInventors: Jukka Seppala, Johan-Fredrik Selin, Tao Su
