    摘要： The present invention provides a method for preparing a customized polymeric article including: providing two mold half-sections, each half-section having an outer surface and an inner surface; assembling the two mold half-sections to form a mold assembly such that the inner surfaces define a cavity there between; applying one or more magnetic fluids to the inner surface of a mold half-section; inserting a fluid polymeric material into the cavity; controllably applying a magnetic field to the magnetic fluids to form a customized reversible surface in accordance with a predetermined specific surface topography; subjecting the mold assembly to conditions sufficient to effect polymerization or hardening of the fluid polymeric material; and separating the two mold half-sections. Articles prepared by the method also are provided.

    摘要： The present invention relates to controlled radical polymerization (CRP) initiators that include at least one radically transferable group. The CRP initiators include at least one of the following, (a) a spirooxazine compound represented by the following Formula (I), and (b) an indenonaphthopyran represented by the following Formula (II), One or more of R1, R2, R3, R4, R5, and R6 of the spirooxazine, and one or more of R7, R8, R9, R10, B, and B′ independently include the radically transferable group. The present invention also relates to polymers, such as mechanochromic polymers, that are prepared from such CRP initiators, polymer compositions that include such polymers, and mechanochromic articles that include such polymer compositions.

    摘要： The present invention is directed to a process for producing a molded polymeric article including: providing a polymerizable composition of a reaction mixture of at least the following components: a mold release agent of ionic fluoride and/or ionic fluoride precursor, and a polymeric organic material selected from thermosetting organic polymeric materials and thermoplastic organic materials; allowing the reaction mixture to undergo exothermic reaction; providing a mold having a first part and a second part spaced one from the other thereby forming a cavity there between; introducing the reaction mixture into the mold cavity wherein the reaction mixture is at a temperature of up to 130° C.; holding the mold at a temperature and for a time sufficient to cure the reaction mixture thereby forming a molded polymeric article within the mold; and removing the molded polymeric article from the mold. Molded articles also are provided.
