Patent number: 11572461Abstract: The present invention is directed to a multimodal polyethylene copolymer comprising a first and a second copolymer of ethylene and at least two alpha-olefin comonomers. Such multimodal copolymers are highly suitable for conversion processes that require a high Draw Down Ratio, like the production of thin films. Such multimodal polyethylene copolymers provide a good impact strength in the sense of a high Dart drop impact strength (DDI) and good isotropy of the films produces thereof. The invention further presents final articles such as films made therefrom.Type: GrantFiled: May 30, 2016Date of Patent: February 7, 2023Assignee: Borealis AGInventors: Ravindra Tupe, John Jamieson, Jarmo Kela, Alexandra Romina Albunia, Ricardo Godoy-Lopez, Markku Vahteri

Patent number: 10619036Abstract: The present invention is directed to a multimodal polyethylene copolymer comprising a first and a second copolymer of ethylene and at least two alpha-olefin comonomers. The multimodal polyethylene copolymer is highly suitable for the production of films providing high impact strength in the sense of high Dart drop impact strength (DDI) and low extractables. The invention further presents final articles such as films made therefrom.Type: GrantFiled: May 30, 2016Date of Patent: April 14, 2020Assignee: Borealis AGInventors: Ravindra Tupe, John Jamieson, Jarmo Kela, Alexandra Romina Albunia, Ricardo Godoy-Lopez, Markku Vahteri

Patent number: 10392460Abstract: The present invention provides a process of producing a modified polymer composition, which composition comprises a free-radical polymeriseable monomer grafted to a polyolefin backbone. The process comprises contacting, in an extruder, an olefin polymer and the free-radical polymeriseable monomer in the presence of a stable radical in an extruder and extruding the composition.Type: GrantFiled: September 11, 2015Date of Patent: August 27, 2019Assignee: BOREALIS AGInventors: Ricardo Godoy-Lopez, Floran Prades, Anh Tuan Tran

Patent number: 8544658Abstract: The present invention relates to a method of preparing RAFT, ATRP or NMRP functionalized thin film composite (TFC) polyamide membranes on a microporous substrate. A further aspect of the invention is the subsequent modification of the thin film composite polyamide membrane by controlled free radical polymerization (CFRP) to yield membranes having new chemical and physical properties, e.g. antifouling and/or antibacterial properties. Further aspects of the invention are the functionalized thin film composite (TFC) polyamide membranes on the microporous substrate itself and the membranes modified by controlled free radical polymerization.Type: GrantFiled: August 3, 2009Date of Patent: October 1, 2013Assignee: Polymers CRC LimitedInventors: Marina H. Stenzel, Ricardo Godoy-Lopez, Simon Harrisson, Ezio Rizzardo

Publication number: 20120053342Abstract: The present invention provides methods of forming carbamates, ureas, and isocyanates. In certain embodiments these methods include the step of reacting an amine with an ester-substituted diaryl carbonate to form an activated carbamate which can be further derivatized to form non-activated carbamate or a urea. The urea or carbamate can be subjected to a pyrolysis reaction to form isocyanate.Type: ApplicationFiled: November 4, 2011Publication date: March 1, 2012Applicant: SABIC INNOVATIVE PLASTICS IP B.V.Inventors: Hatem Abdallah Belfadhel, Hans-Peter Brack, Ricardo Godoy-Lopez, Dennis James Patrick Maria Willemse

Patent number: 7977447Abstract: A method for forming a monomeric carbonate includes the step of combining a monofunctional alcohol or a difunctional diol with an ester-substituted diaryl carbonate to form a reaction mixture. Similarly, a method for forming a monomeric ester includes the step of combining a monofunctional carboxylic acid or ester with an ester-substituted diaryl carbonate to form a reaction mixture. These methods further include the step of allowing the reaction mixtures to react to form a monomeric carbonate or a monomeric ester, respectively.Type: GrantFiled: December 24, 2008Date of Patent: July 12, 2011Assignee: Sabic Innovative Plastics IP B.V.Inventors: Hatem Abdallah Belfadhel, Hans-Peter Brack, Ricardo Godoy-Lopez, Dennis James Patrick Maria Willemse
