The properties of the polymeric polyols depend on the type of plant oil used as starting material. Typically, polymeric content of the purified plant oil based polyols ranges from 65% to 90%. The hydroxyl value and the acid value ranges from 30 to 90 mg KOH/g sample and 1 to 14 mg KOH/g sample respectively. The average molecular weight Mn ranges from 800 Da to 16000 Da. The liquid plant oil based polymeric polyols are reacted with excess diisocyanate to produce isocyanate terminated prepolymer. Subsequently, the prepared prepolymer is reacted with diol or diamine to polyurethane and polyurea respectively.Type: GrantFiled: October 18, 2012Date of Patent: August 26, 2014Assignee: Malaysian Palm Oil BoardInventor: Hoong Seng Soi

Patent number: 8784990Abstract: Provided is a resin composition based on polyalkylene carbonate for use as an adhesive film composition for glass lamination, and more particularly, to a resin composition in which a plasticizer and isocyanate are added to polypropylene carbonate or polyethylene carbonate as polyalkylene carbonate to introduce a urethane group. As such, the resin composition of the present invention can improve an adhesive strength by addition of isocyanate, and secure flexibility by using the plasticizer. In particular, an adhesive sheet based on polyalkylene carbonate can decompose a polymer laminate layer through simple heat treatment to fully collect glass when defects of glass lamination are generated, thereby reducing the loss of glass due to process failure, be stable to moisture so that transport, storage, and use thereof are not limited, and perform lamination even at a lower process temperature.Type: GrantFiled: October 6, 2011Date of Patent: July 22, 2014Assignee: SK Innovation Co., Ltd.Inventors: JaeYoung Park, SeungGweon Hong, HyeLim Kim, KwangJin Chung, MyungAhn Ok

Publication number: 20140200324Abstract: Processes for the production of polyols from sources such as dried distillers grains plus solubles (DDGS) make use of a two-stage reaction scheme. In the first stage, the proteinaceous starting material is reacted with an aminating agent, such as diethanolamine (DEOA), to generate amino-amides and amides. These products are then reacted with an alkoxylating agent, preferably a substituted or unsubstituted epoxide to yield polyols. These polyols may be further reacted with isocyanates to give low-cost rigid polyurethane foams. In alternate forms, lignin may be directly converted to polyols by reaction with an alkoxylating agent, optionally followed by reaction with an isocyanate to produce polyurethanes.Type: ApplicationFiled: February 1, 2013Publication date: July 17, 2014Applicants: PITTSBURG STATE UNIVERSITY, MGPI PROCESSING, INC.Inventors: Sukh Bassi, Michael Douglas Parker, Mihail Ionescu, Zoran Petrovic
