    Abstract: The present invention relates to novel polymeric compositions that exhibit Reverse Thermal Gelation (RTG) properties for use as Support Materials (SM) in the manufacture of three-dimensional objects. These polymers are Temperature Sensitive Polymers that respond with a significant change of properties to a small change in temperature. Temperature Sensitive Polymers exhibit cloud point (CP) or lower critical solution temperature (LCST) in aqueous solutions. Water-soluble Temperature Sensitive Polymers are chosen to give low viscosity liquid at low temperature when dissolved in water and by that to permit easy dispensing at low temperature. Raising the temperature above their gelation temperature (Tgel) will result in solidification of the composition. At its gel position the material has favorable characteristics as a support and building material. The gel layers have the appropriate toughness and dimensional stability to support the model layers during the building process.

  • Patent number: 6914086
    Abstract: A crosslinkable UV absorbing agent prepared by the following steps: (1) preparing a mixture of reactants comprising a UV absorbing compound (A) with multiple pendant hydroxyl groups and an unsaturated monoglycidyl compound (B) with both reactive glycidyl and vinyl groups; (2) mixing a base catalyst (C) with the mixture of reactants; (3) initiating a synthesis reaction of the crosslinkable UV absorbing agent under heating; and (4) recovering the resulting product after the synthesis reaction is completed. The crosslinkable UV absorbing agent is directly applicable in the lens formulation to replace conventional crosslinking agent and UV absorber used in the production of the soft contact lens without any purification or modification.

  • Patent number: 6686008
    Abstract: The invention is a composition made by mixing a multifunctional acrylate with an aminofunctional silane and an ethylenically unsaturated acid to form a reaction product, optionally dissolved in a solvent, characterized in that the multifunctional acrylate has a molecular weight of from about 100 to about 3000. The composition can be coated on a substrate, then optionally exposed to moisture and treated to initiate a free radical reaction. The invention can be applied to a variety of substrates used in packaging applications. The reaction mixture can further be cured by heating in the presence of moisture. The free radical reaction can be initiated by electron beam irradiation, ultraviolet radiation, gamma radiation, and/or heat and chemical free radical initiators.

  • Patent number: 6669994
    Abstract: A method of forming a polymer layer on a support surface by the use of a coating agent and polymerizable compounds. The coating agent provides photoreactive groups adapted to attach the agent to the surface, as well as photoreactive groups adapted to remain unattached to the surface, and thus serve as photoinitiators for the activation of polymerizable compounds in order to form a polymer layer thereon. Also provided are coating agents, per se, as well as a method of using such agents and the resultant surfaces and devices fabricated therefrom.
