摘要： A new concept in polymeric prosthetic devices having a portion thereof composed of a hydrophilic polymer is described herein in which distortions and stresses upon the device due to water absorption are minimized or eliminated. Physical properties of the various portions of the device may thus be varied to provide the particular physical parameters required. Compositions of matter and methods of manufacturing the novel prosthetic devices are described. The composition of matter is a polymer which includes a water soluble solid inert substance removable by exposure to water during hydration of the hydrophilic portion of the device, thus eliminating distortions and stresses therein. The hydrophilic polymer described is useful, for example, as one component part of such prosthetic devices as a hard-soft contact lens, cardiovascular implants, etc. useful in aqueous environment wherein stress and deformation of the polymer shape due to hydration must be minimized.
摘要翻译：本文描述了具有由亲水性聚合物组成的部分的聚合物修复装置中的新概念，其中由于吸水而使装置上的变形和应力最小化或消除。因此可以改变装置的各个部分的物理性质以提供所需的特定物理参数。描述了物质的组成和制造新型假体装置的方法。物质的组成是一种聚合物，其包括在装置的亲水部分水合期间通过暴露于水而可去除的水溶性固体惰性物质，从而消除其中的变形和应力。所描述的亲水性聚合物可用作例如可用于水溶液环境中的硬质隐形眼镜，心血管植入物等这样的假体装置的一个组成部分，其中由于水合而使聚合物形状的应力和变形必须最小化。

摘要： A method for providing hydrophilic contact lenses with identifying means incorporated into lens blanks and the resulting lenses in which an elongated identifying strand, fiber, or rod is molded into a cylindrical lens blank rod positioned substantially parallel to the axis of the rod. Lens blanks or buttons are cut transversely to the axis and the lens blanks ground to the proper optical curvatures. The contact lens blanks each contain portions of the identifying means. The finished contact lenses each contain short segments of the identifying means thereby allowing classification of the contact lenses as to right or left eye, magnification power or other characteristic.

摘要： The present invention provides compositions, useful for making lyocell fibers, having a high hemicellulose content, a low copper number and including cellulose that has a low average degree of polymerization (D.P.) and a narrow molecular weight distribution. Further, the present invention provides processes for making compositions, useful for making lyocell fibers, by contacting an alkaline pulp having a high hemicellulose content of at least about 7% with an oxidant sufficient to reduce the average degree of polymerization to about 200 to 1100 without substantially reducing the hemicellulose content or increasing the copper number of the pulp.
