Abstract: Processed plant fine fibers such as those from the mesocarp of a coconut together are blended with a biodegradable plastic to produce a biodegradable plastic product that can be further made into other items. Plastics thus made from coconut husk fine fiber powder will return to the environment after disposal much more rapidly than those without coconut husk fine fiber powder. In the process, a dry compressed plant fine fiber powder is created from fine fibers of the coconut mesocarp. An example product created from this raw material is composed of 10 to 40% by weight of dry coconut husk powder mixed with environmentally degradable plastic. Environmentally non-degradable plastic may be added to the dry powder as a biodegradation rate modulator to create a modified raw material with a modified biodegradation rate. Plastic additives, standard in the industry, can be added to achieve additional desired properties. For example, a surface active agent may be added in order to increase the degree of processability; a colorant may be added to increase marketability; pesticides may be added as needed in order to protect the product or the soil in which the product is disposed from insects; and/or polymerization modifiers such as cross-linkers, monomer derivatives, heteromonomers, curing agents, etc. may be utilized to vary the properties of the base plastic.

Abstract: The present invention relates to a process for obtaining polyarylene sulfide from polyarylene sulfide-containing material. For this purpose, the polyarylene sulfide-containing material is treated with a solvent in which it dissolves, and is subsequently reprecipitated. The invention also relates to the purification of polyarylene sulfide-containing material by separating off extraneous substances, to polyphenylene sulfide particles having a specific surface area of at least 80 m.sup.2 /g and to their use as filter material.

Abstract: Cyclic N-halamine biocidal monomers and polymers and methods of using the same as biocides, wherein the functional group, halogenated oxazolidinones, may be homo- and copolymerized, are provided. The copolymerizations are effected with inexpensive monomers such as acrylonitrile, styrene, vinyl acetate, vinyl chloride, and the like. Grafting reactions were also accomplished with the N-halamine monomers and commercial polymers such as poly-acrylonitrile, poly-styrene, poly-vinyl acetate, poly-vinyl alcohol, poly-vinyl chloride, and cellulose. These N-halamine compounds are stable biocides which release small amounts of free halogen and other impurities. They will be useful as disinfectants for swimming pools, oil and water based paints, preservatives, medical and dental coatings, industrial and commercial coatings, fabrics, sterile bandages, liners of containers, and the like.
