  • Patent number: 11718711
    Abstract: A method and a facility produce polylactide (PLA) by polymerization, in which a lactide mixture is mixed with at least one catalyst, is introduced into a modular planetary roller extruder and the finished PLA is then removed. The lactide mixture continuously passes through segments of the extruder. The course of the reaction is measured and controlled in the segments in a targeted manner such that the temperature can be set by heating and/or cooling. The pressure can be variably set depending on pressure values to be checked by a controllable gas extraction and/or a controllable extruder speed and/or static variability of the planetary rollers and/or a variable metering speed of the lactide mixture and/or a variable mixing ratio of the lactide mixture. Flammable gas is removed in an explosion-protected zone in a partial region of the extruder. Additives are introduced into the extruder during the rolling process.

  • Publication number: 20100093917
    Abstract: A method for producing a water absorbent resin comprises the steps of: (i) polymerizing a monomer including an unsaturated monomer containing a carboxyl group, in the presence of an internal cross-linking agent (A) having two or more radical polymerizable unsaturated groups in its single molecule and in the presence of a non-polymeric internal cross-linking agent (B) having in its single molecule two or more functional groups each of which allows formation of an ester bond or an amide bond by reacting with a carboxyl group, while crushing a cross-linked polymer hydrogel; and (ii) drying the cross-linked polymer hydrogel obtained in the step (i), wherein: an amount of the internal cross-linking agent (A) is 0.01 mol % or more and 0.2 mol % or less relative to an amount of the unsaturated monomer containing a carboxyl group, and a molar ratio (B)/(A) of the internal cross-linking agent (A) and the non-polymeric internal cross-linking agent (B) is 0.01 or more and 1.8 or less.

  • Publication number: 20100092713
    Abstract: A screen protector for use on a mesh screen in a screen printing process can include a layer of protective material such as a polyester film, and a pressure sensitive adhesive on a surface of the polymeric film for adhering the layer to the mesh screen. The screen protector supports the mesh screen and helps prevent premature fraying of the screen. The adhesive can be an acrylic based pressure sensitive adhesive that substantially retains its adhesion properties when in contact with ink. The protector remains substantially attached to the mesh screen when in contact with ink, and therefore no filler material is needed.

  • Publication number: 20100029848
    Abstract: A process for producing an epoxide such as a cycloaliphatic diepoxide by the reaction of an olefin such as a cycloaliphatic diene with hydrogen peroxide (H2O2) as an oxidant in the presence of a catalytic system under pH control for example at a pH of less than about 5. The present invention is advantageously used for the epoxidation of olefinic compounds such as olefins and aliphatic or aromatic dienes.
