  • Antifouling composition
    Patent number: 10954395
    Abstract: A binder for a marine coating composition comprising the reaction product of a polysiloxane unit A? and at least one second monomer B? that undergoes a polymerisation reaction with said polysiloxane unit A? so as to form a copolymer of structure -[ABAB]- wherein the backbone of said copolymer comprises a plurality of hydrolysable ester functional groups that will hydrolyse in the presence of seawater.

  • Multi-stage process for producing multimodal linear low density polyethylene polymers
    Patent number: 8461280
    Abstract: A multimodal linear low density polyethylene polymer having a final density of 900 to 940 kg/m3, and containing at least one ?-olefin comonomer in addition to ethylene comprising: (A) 30 to 60 wt % of a lower molecular weight component being an ethylene homopolymer or a copolymer of ethylene and at least one ?-olefin; and (B) 70 to 40 wt % of a higher molecular weight component being a copolymer of ethylene and at least one ?-olefin, said ?-olefin being the same or different from any ?-olefin used in component (A) but with the proviso that both components (A) and (B) are not polymers of ethylene and butane alone; wherein the multimodal LLDPE has a dart drop of at least 700 g; and wherein components (A) and (B) are obtainable using a Ziegler-Natta catalyst.
