  • Publication number: 20100151190
    Abstract: The present invention relates to a multilayer protective enclosure for protecting humans, animals or perishables from hazardous agents in the environment. The enclosure contains a porous adaptive membrane structure that has movable membranes with insertable protrusions. The structure can be made to change its gas, liquid or particulate permeability in response to surrounding environmental conditions. Hence, the enclosure is highly breathable in a non-hazardous environment but impermeable or only semipermeable in a hazardous environment.

  • Patent number: 6835335
    Abstract: A process for forming solid particles comprising the steps of: combining in molten form a major component of a crystallizable condensation homopolymer and a minor component of a non-crystallizable condensation polymer, wherein the crystallizable condensation homopolymer and the non-crystallizable condensation polymer each have a degree of polymerization of 10 to less than 48 prior to the combining; mixing the combined crystallizable condensation homopolymer and non-crystallizable condensation polymer in molten form to form a mixture that comprises 10 to 30 mol % of the non-crystallizable condensation polymer; forming the mixture into droplets; exposing the droplets to a thermal environment which results in the bulk of the droplet reaching within 15 seconds a temperature within ±10° C.
