METHODS AND COMPOSITIONS FOR POLYMER MATRIX SYNTHESIZED BY POLYCONDENSATION

摘要

The present invention relates to packaging material/matrix and methods of making such packaging material/matrix for slow or extended release of at least one active volatile compound(s). Provided are methods and compositions for a polymer matrix incorporating at least one active volatile compound (for example 1-methylcyclopropene or 1-MCP) and the polymer matrix is synthesized by polycondensation. This polymer matrix can slowly release the active volatile compound after contacting with a solvent (for example moisture). Also provided is the use of such polymer matrix to prolong the shelf-life of fruits and vegetables.
