    Abstract: The exemplary embodiments disclosed herein relate to activating methods for initiation polymerization of methylene malonates and other polymerizable compositions. The polymerization may be activated by anionic or free radical mechanisms. Because the polymerization may occur very quickly upon contact between the activating agent and the polymerizable composition, methods are provide herein for separating or otherwise rendering the activating agent ineffective to initiate polymerization, until such a reaction is desired. The separation may be physical (separate packaging, separate application steps, encapsulation) or it may be based on latent-activation methods (activation precursors, UV activation). Products formed from the methods disclosed herein may include inks, adhesives, coatings, sealants, reactive moldings, fibers, films, sheets, medical polymers, composites, laminates and the like.

  • Patent number: 8378033
    Abstract: The present invention relates to a method of producing water-absorbent resin particles in which a median particle size of primary particles (d) and a median particle size of secondary particles (D) satisfy the relationship of the formula, 5d/3+150<D<5d+150, comprising the steps of: (1) subjecting a water-soluble ethylenically unsaturated monomer to a first-step reversed phase suspension polymerization reaction, in a petroleum hydrocarbon solvent, in the presence of a dispersion stabilizer, to give spherical primary particles having a median particle size (d) of from 30 to 130 ?m; (2) cooling the polymerization reaction solution, to precipitate the dispersion stabilizer; and (3) carrying out a second-step reversed phase suspension polymerization reaction by adding the water-soluble ethylenically unsaturated monomer for the second step to the polymerization reaction solution to agglomerate the primary particles, to give secondary particles having a median particle size (D) of from 200 to 500 ?m.

  • Patent number: 8349912
    Abstract: Crosslink agents used to copolymerize at least one hydrophilic monomer with at least one lens monomer typically used to prepare polymeric materials for ophthalmic lenses. The crosslink agents have a relatively high selectivity for the hydrophilic monomer and limited reactivity with the crosslink agent used to polymerize the lens monomer. Accordingly, the invention is also directed to a hydrophilic crosslinked polymer that comprises at least two monomeric units and at least two different crosslink units. The use of the dual crosslink system provides an improved means to control the final chemical, physical and structural characteristics of the resulting polymer.

  • Publication number: 20120291793
    Abstract: The invention provides a method of isolating certain target compounds from tobacco, tobacco materials or smoke generated by a smoking article. The method can be used to remove undesirable compounds from tobacco, tobacco materials, or tobacco smoke. The method can also be used to remove flavor compounds from tobacco or tobacco materials, which can then be used as flavor components for tobacco material used in smoking articles and smokeless tobacco compositions.
