Abstract: The polymer composition is used for packing products of the chemical, food and other industries. The packing material obtained from the polymer composition has a wide range of application and controllable decomposition of the packages in water medium, ensuring environmental cleanness and recycling of the material. The polymer composition for packing materials contains polyvinylalcohol and water, and, according to the invention, it also contains polyvinylacetate dispersion, methylcellulose, carboxymethylcellulose and glucose in the following proportions of the components in % by weight: polyvinylalcohol 32-84, polyvinylacetate dispersion 10-57, methylcellulose 3.0-5.8, carboxymethylcellulose 2.0-4.2, glucose 0.5-2.3, and water 0.5-6.0. The method for producing packing materials from the polymer composition includes the preparation of a dry mixture or viscous mass and moulding. According to the invention, before or after the moulding the material is treated successively with aqueous sodium tetraborate solution and aqueous formaldehyde solution.

Abstract: The present invention teaches a chemiluminescent device along with a process for its production. The invention specifically relates to a chemiluminescent article of manufacture which includes a containment device and chemical system, both of which may be selected so as to be particularly susceptible to environmental degradation subsequent to their use. In a preferred embodiment the chemiluminescent device is categorized as being biodegradable, i.e. designed to be capable of losing its physical form and re-entering the environment.
