  • Publication number: 20240026145
    Abstract: The present invention provides an ocular lens which achieves both of oxygen permeability and surface hydrophilicity, and on which the deposition of lipids is suppressed. The ocular lens of the present invention includes a polymer material obtained by polymerizing a polymerizable composition containing, as monomer components, a siloxane monomer having a siloxane bond, and a siloxane-free crosslinkable monomer free of any siloxane bond, wherein the siloxane-free crosslinkable monomer includes an alkylene glycol chain-containing crosslinkable monomer having: a chain moiety containing 6 or more alkylene glycol repeating units; and polymerizable groups arranged at both terminals of the chain moiety.

  • Patent number: 11124907
    Abstract: The present invention provides a spun-bonded nonwoven fabric which is configured from polyolefin fibers that have excellent spinnability even if the single fiber diameter thereof is small, and which exhibits high flexibility and high uniformity. The present invention relates to a spun-bonded nonwoven fabric which is configured from fibers that are formed from a polyolefin resin and have a single fiber diameter of 6.5-14.5 ?m, and which has a melt flow rate of 155-850 g/10 minutes and a CV value of the thickness of 13% or less.
