  • Publication number: 20230159139
    Abstract: A foamable composition for injecting in a region of a ship, for example to prevent and/or reduce water ingress and/or progressive flooding in the ship so as to improve damage stability of the ship, is foamable to form a foam and is dissolvable in a removal composition. The provision of a foam, which can be dissolved by application of a removal composition, e.g., a solvent, may improve ease of removal of the foam, and therefore may reduce the cost and/or speed of reinstatement of the ship. The present invention also relates to a method of improving damage stability of a ship, the method comprising identifying one or more regions of the ship where injection of a material may lead to increase in ship stability, the material being impermeable to water and/or being capable of preventing migration of water.

  • Patent number: 11572461
    Abstract: 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.
