  • Method for encapsulating pollutants from water using modified dendrimeric polymers
    Patent number: 7767091
    Abstract: The invention deals with lipophilic modified dendrimers and hyperbranched polymers that can encapsulate organic pollutants of a diversity of sizes and shapes and which are prepared following the modification of the functional groups present at the surface of the polymer. These functional polymers are characterized by the fact that their nanocavities do not have predetermined dimensions but their size and shape are affected by the size and shape of the pollutant they will encapsulate or otherwise they will be so-adjusted to it.

  • Silylation of epoxy-containing photoresist films
    Patent number: 6296989
    Abstract: A high resolution pattern transfer processes is described, whereby epoxy containing photoresist films are imagewise exposed to radiation, baked to crosslink the exposed areas, and treated with a silylating medium, which reacts with the epoxy ring thereby incorporating silicon at will in the non-crosslinked regions of the film, while making those regions resistant to oxygen atom-containing plasmas.
