Lewis A. Gugliemelli 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).

  • Composite compositions from graft polymerized rigid fillers
    Patent number: 4026849
    Abstract: Filled composite plastics are prepared, which consist entirely of a rigid filler which has been graft polymerized with a thermoplastic polymer. The conventional thermoplastic matrix has been eliminated. When the rigid filler is a polysaccharide, such as starch, a product with improved biodegradability is produced. Also, valuable petroleum reserves are conserved, since the polysaccharide portion serves as an extender for the petroleum-based polymer.

  • Preparation of graft polymer latexes by sonification
    Patent number: 3984361
    Abstract: Starch graft polymer latexes as well as processes for their preparations are disclosed. The starch graft latexes are water-dispersed grafted starch particles (300-1500 A in size) consisting of either (1) a cationic starch graft polymerized with up to 66% by weight of either nonionic or cationic vinyl monomers alone or with selected combinations thereof or (2) a nonionic starch graft polymerized with a cationic monomer alone or in combination with nonionic monomers. The latexes, having a range of properties, dry at 25.degree. C. or at higher temperatures to clear continuous films.
