ABSTRACT:
Hydrophilic composite polymer articles are provided which comprise at least one hydrophilic polymer in a powder form and one or more liquid components of which at least one is hydrophilic and which can be polymerized with said hydrophilic polymer. This composition is produced from a homogeneously mixed paste which can be molded or cast into a desired shape which will subsequently set. The resulting article has a shape-retaining, non-tacky flexible consistency which allows the shape to be further modified, if necessary.
Such object can be then cured by any of the conventional curing methods to retain its shape permanently. The final properties of the composite can be tailored to suit the final application by using fillers or modifiers. In the medical field, such articles can be utilized as a sustained release devices as they can be loaded with the desired therapeutic drugs. These articles can be made non-toxic and biocompatible and used as prosthetic devices.
The final cured article can be modified further by polishing, drilling, cutting, etc. When exposed to moisture or a humid environment, the article will become partially hydrated with a resultant softer surface yet retain good mechanical strength.
