Guido P. C. Beusen 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: 6548181
    Abstract: The invention relates to a flexible polyamide composition containing at least 50 parts by weight of non-cross-linked rubber per 50 parts by weight of polyamide and the production thereof. The polyamide has a molecular weight such that the melt viscosity at the processing temperature is at most 300 pa.s, preferably at most 200 pa.s. The rubber's Mooney viscosity is at least 40, most preferable is a rubber with a Mooney viscosity of at least 60. The rubber has been functionalized. Preferably a combination of a functionalized and a non-functionalized rubber is used. The rubber particles in the polyamide matrix have a particle size of at most 5 &mgr;m, preferably at most 3 &mgr;m.

  • Publication number: 20020039630
    Abstract: A container comprises a wall comprising at least one layer, the wall comprising a polypropylene having a high flexural modulus and a polyethylene chosen from low-density and very low-density polyethylenes. The container can further comprise a product in the container. The product is chosen from cosmetic products, food products, household products, and industrial chemistry products. A method of making the container includes extruding a parison having at least one layer, the parison including a polypropylene having a high flexural modulus and a polyethylene chosen from low-density and very low-density polyethylenes, and blowing the parison in a mold having at least one cavity with a geometry corresponding to that of the container to obtain the container.

  • Patent number: 5859148
    Abstract: The invention relates to a process for the preparation of star-branched polymers by reaction in the melt of a polymer having at least one hetero atom in the chain with a compound having at least three functional groups. Suitable polymers are for instance polyamides, polyesters, polyurethanes, polyoxyalkyls, polyimines and copolymers of these. Functional groups are for instance amine, carboxyl, hydroxyl, isocyanate and imine groups. The process is very fast and requires no special purification. The process enables star-branched polymers to be prepared which are derived from so-called AABB polycondensates.
