    摘要: A composition of macrocyclic oligomer with at least one (meth)acrylate polymerizable group. A method includes preparing an activated precursor of an oligomer at pseudo high-dilution conditions. A method also includes preparing an activated precursor of an oligomer by reacting the precursor with an activated coupling agent, wherein the precursor is condensable and polymerizable.

    摘要: A photopolymerizable material is exposed to light to effect curing. A portion of the material is exposed to light in a conventional manner, while at least one other portion of the material is masked from direct exposure to the light by use of a mask (10) having at least one mask segment (11) which either completely or at least partially blocks the light. In this manner, the polymerization stress associated with the cured materials is limited or minimized due to extended molecular relaxation promoted by this controlled or hybrid curing technique. Also according to the invention, different segments (30, 31) of a material to be cured (22) are exposed to different wavelengths of light energy (21) or one such segment (30, 31) is exposed to light energy while another such segment is not.
