Abstract

The anionic ring-opening polymn. of episulfides has been successfully applied in emulsion. The polymn. proceeded with a living mechanism but was characterized by a limiting conversion, presumably arising from the increase in viscosity in the polymer. To the knowledge of the authors, only two other cases of living anionic polymn. in emulsion are known (silicones and cyanoacrylates); the addnl. novelty presented by episulfides is the ease of end-functionalization. Furthermore, the emulsion polymn. allowed the prepn. of highly stable particles, which, due to their PEGylated surface and their appropriate diam., can be applied in the biomedical field as nanocarriers.

Related concepts (8)

Novelty (patent)

Novelty is one of the patentability requirement for a patent claim, whose purpose is to prevent issuing patents on known things, i.e. to prevent public knowledge from being taken away from the public domain. An invention is anticipated (i.e. not new) and therefore not patentable if it was known to the public before the priority date of the patent application. Although the concept of "novelty" in patent law appears simple and self-explanatory, this view is very far from reality.

Biomedical engineering

Biomedical engineering (BME) or medical engineering is the application of engineering principles and design concepts to medicine and biology for healthcare purposes (e.g., diagnostic or therapeutic). BME is also traditionally logical sciences to advance health care treatment, including diagnosis, monitoring, and therapy. Also included under the scope of a biomedical engineer is the management of current medical equipment in hospitals while adhering to relevant industry standards.

Applied science

Applied science is the use of the scientific method and knowledge obtained via conclusions from the method to attain practical goals. It includes a broad range of disciplines such as engineering and medicine. Applied science is often contrasted with basic science, which is focused on advancing scientific theories and laws that explain and predict natural or other phenomena. Applied science can also apply formal science, such as statistics and probability theory, as in epidemiology.
