Preparation of artificial viscoelastic agent / 中国康复理论与实践

ABSTRACT

@#ObjectiveTo prepare artificial viscoelastic agent used in ophthalmic operation as a substitute of Healon. MethodsPolyacrylamide was synthesized in aqueous solution of acrylamide. Residual monomer(Am) was separated from polymer by a novel method, extraction by semi permeable film. Results and ConclusionsArtificial viscoelastic agent prepared has advantages on cost of manufacture, processing repeatability and stability of storage comparing to Healon.
