LIGHT REFLECTIVE, SELF-ASSEMBLING BLOCK COPOLYMER FILM OR COATING, METHODS FOR THEIR PREPARATION AND USE THEREOF

Номер: CA0002806534A1
Принадлежит:

A multilayer light reflective self assembly film or coating which reflects light of a desired wavelength is obtained by blending block copolymer fractions of different molecular weight. The colour of light reflected by the film or coating depends on the relative amounts of the block copolymers in the blend. Thus, the colour of the reflected light is selectable by varying the relative amounts of the block copolymers in the blend. The polymers may be cross-linked by means of a suitable cross-linking agent. Applications of the film or coating include anti- counterfeiting devices.

Photopolymerizable biodegradable hydrogels as tissue contacting materials and controlled-release carriers

Номер: US0005626863A1

Hydrogels of polymerized and crosslinked macromers comprising hydrophilic oligomers having biodegradable monomeric or oligomeric extensions, which biodegradable extensions are terminated on free ends with end cap monomers or oligomers capable of polymerization and cross linking are described. The hydrophilic core itself may be degradable, thus combining the core and extension functions. Macromers are polymerized using free radical initiators under the influence of long wavelength ultraviolet light, visible light excitation or thermal energy. Biodegradation occurs at the linkages within the extension oligomers and results in fragments which are non-toxic and easily removed from the body. Preferred applications for the hydrogels include prevention of adhesion formation after surgical procedures, controlled release of drugs and other bioactive species, temporary protection or separation of tissue surfaces, adhering of sealing tissues together, and preventing the attachment of cells to tissue ...
