Slow-release agent

Applications. These materials are stiU in developmental infancy. Current production is limited to one commercial process in Europe and a demonstration-scale process in North America. The lignins produced in these processes have potential appHcation in wood adhesives, as flame retardants (qv), as slow-release agents for agricultural and pharmaceutical products, as surfactants (qv), as antioxidants (qv), as asphalt extenders, and as a raw material source for lignin-derived chemicals. 

This compound was essentially non-toxic to house flies by topical application but showed moderate activity against the green rice leafhopper and brown planthopper as a residual spray. These results raise the possibility of applying derivatization reactions for the synthesis of polymeric insecticidal materials which may act as slow release agents. 

Schuerch2) reviewed the medical application of synthetic poly-saccharides. Capozza199 reported that the poly-orthoester prepared from 2-ethoxy-4-hydroxymethyl-l,3-diox-olane in the presence of add are useful as slow-release agents for drugs. Poly-2,6,7-trioxabicyclo[2.2.1]heptane VIII showed the same behavior200).
