Patents by Inventor Erich Meusel

Erich Meusel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7342061
    Abstract: The invention relates to a method for producing novel reactive organic compounds containing poly-DOPO and having a higher phosphorus content than known comparable DOPO (9,10-dihydro-9-oxa-10-phospha-phenenthrene-10-oxide) adducts, and to the use thereof for flameproofing thermoplastic polymers, such as polyesters and polyamides. The same flameproofing effect is achieved with smaller additive quantities than previously, thus reducing the influence of the physical, especially textile-physical properties of the polymers. The adducts containing poly-DOPO are formed by reacting DOPO with acetylenes carrying reactive groups, in the presence of a catalyst.
    Type: Grant

  • Patent number: 7009027
    Abstract: This invention relates to a method for producing and processing polyester block copolymers, in particular, polyester side-chain grafted, rigid side-chain and/or semi-rigid side-chain polymers. According to the invention, the monomeric units of rigid side-chain and/or semi-rigid side-chain polymers are, preferably in the melt, polycondensated together with monofunctionalized and/or difunctionalized, cyclic dicarboxylic acid anhydrides to form polymers having anhydride terminal and/or side groups. The formed polyester anhydrides are reacted with the hydroxyl groups and/or with the ester groups of meltable linear polyesters in order to form side-chain grafted, rigid side-chain and/or semi-rigid side-chained polymers and, together with meltable polyesters, they form molecularly reinforced blends.

  • Publication number: 20030149154
    Abstract: This invention relates to the use of organophilic, swellable specially modified phyllosilicates in the production of nano-reinforced thermoplastic polymers, preferably polyamides, polyesters and polycarbonates. The inorganic phyllosilicate particles are bonded to or incorporated into the polymer in a covalent manner with nanodistribution. Special modification enables the phyllosilicates to be used as initiators in the case of polymerization or a chain elements in the case of condensation. The covalent bonding of the phyllosilicate particles to the polymer increases the stability of the reinforcing effect as opposed to an ionic bond. The special modification is performed for phyllosilicates which become hydrophobic as a result of cationic exchange. This property makes it possible for certain organic reaction partners to reach reactive groups present on the surface of the phyllosilicate and to react therewith on certain conditions.
