  • Patent number: 8399581
    Abstract: Metallocene catalyzed polyethylenes are found to have improved physical properties, improved processability and improved balance of properties. Surprisingly, there is a direct relationship between MD shrinkage, and MD tear. Additionally, MD tear is greater than TD tear, and MD tear is also greater than intrinsic tear. MD tear to TD tear ratios are above 0.9, and dart drop impact is above 500 g/mil. The polyethylenes have a relatively broad composition distribution and relatively broad molecular weight distribution.

  • Patent number: 8377551
    Abstract: A structure includes a substrate, a first layer formed on the substrate, and a second layer formed on the first layer. The first layer is comprised of self-assembled monolayer and contains 4-(6-hydroxyhexyloxy)-4?-methoxybiphenyl. The second layer is obtained by micro-phase separation of a block copolymer containing a hydrophilic polymer comprised of polyethylene oxide and a hydrophobic polymer comprised of polymethacrylic acid containing azobenzene at the side chain. The second layer contains a cylinder phase with its long axis being oriented perpendicular to the substrate. The thickness T of the second layer is within a range of A?T?50 nm, where A is a phase separation period length satisfying 5 nm?A?50 nm.

  • Patent number: 8309206
    Abstract: A method of manufacturing an oriented film of thermoplastic polymer material comprises extrusion of a film in tubular form from an extrusion die, orienting the film in a main direction of orientation during the haul-off from the die while in molten or semi-molten state, the direction being at an angle between 0 and 45-to the axis of the tube, followed by cutting of the tube at an angle to its main degree of orientation to form a web having an orientation of no less than 20 to its longitudinal direction, which method involves segmental stretching of the film to form an array of linear bosses (1), being of thicker material, integrally connected by thinner webs (2), said bosses and webs extending in a direction which is generally parallel with the direction of orientation, forming an acute angle to the longitudinal direction of the web, the method involving, after segmental stretching and cutting, shearing of the bosses along one another under re-orientation in the connecting webs, to increase the angle at which
