| 摘要 |
<p>The present invention refers to a process for the production of controlled-releaseaqueous compositions comprising an active ingredient releasably containedwithin polymeric particles. The polymeric particles are obtainable by ring-openingmetathesis polymerisation of a monomer of the general formula (I) wherein R and R have the same meaning as given in the specification, or a mixture thereof,in an aqueous phase in the presence of a ruthenium catalyst, an emulsifier, andan active ingredient.</p> |
