Definitions

  • the present invention refers to new, biodegradable plastic materials, in particular to new plastic materials obtained syn- thetically.
  • plastic materials have become more and more popular, a process which has been ongoing for many years now.
  • plastic materials share the advantage of combining good mechanical properties and chemical stability properties with a relative thermal stability, with the inertia in reactions with the main chemicals and with low manufacturing costs .
  • the above mentioned chemical inertia has as a negative consequence the fact that the plastic materials are often difficult to dispose of, thereby piling up in the environment.
  • plastic materials capable of decomposing independently and in a reasonable time have been devised.
  • Plastic materials capable of biodegrading have then been studied, for example the material known as Mater Bi.
  • the object is achieved though a plastic material obtained from- monomers comprising functional groups, characterised in that said functional groups are partly replaced by homologous functional groups of proteins .
  • the present invention is focused on imparting a certain degree of biodegradability to synthetic polymers, normally only little disposable.
  • polyurethanes poly- ethylenterephtalate, polypropyletherphtalate, ethylene and vinyl acetate (EVA) copolymer, nylon, rayon, polyvinyl chloride (PVC) can be cited in particular.
  • EVA ethylene and vinyl acetate
  • nylon nylon
  • PVC polyvinyl chloride
  • PVC polyvinyl chloride
  • thermoplastic polyurethanes are preferred. These are linear polymers with rigid segments and flexible segments. In them, the rigid segment consists of aromatic or aliphatic isocyanates, bonded to short-chain diols.
  • the flexible segment can consist of units of polyethere or of polyester and is chosen based on the applications for which it is used.
  • the ethylene and vinyl acetate copolymer preferably comprises a content of vinyl acetate ranging between 5 and 80%, preferably between 7 and 50%, most preferably between 10 and 40%.
  • This material advantageously combines elastomeric properties with thermoplastic properties.
  • the functional groups are partly replaced by reaction with proteins, i.e. with biopolymeric structures which have a number of func- tional groups useful for copolymerisation with synthetic monomers.
  • an amount of protein is employed varying between 0.2 and 80%, more preferably between 1 and 70%.
  • An optimal product is obtained by adding between 1.5 and 60% of protein. The percentages are by weight, based on the finished product. Any protein can be used. Particularly advantageous, for reasons of economy and availability, proved egg white and the proteins obtained by squashing soy beans, rapeseed, sunflower and corn germ.
  • the protein is simply mixed to one of the monomers before the polymerisation reaction, so that said reaction occurs at a temperature ranging between 20° C and 250 0 C with the direct replacement of a part of the functional groups.
  • the protein partially replaces the polyols used for polymerisation, while in the case of the copolymer ethylene/vinyl acetate, the protein partially replaces vinyl acetate.
  • a monomer containing functional groups is replaced by the protein providing func- tional groups of similar reactivity, so that, in the end polymer, part of the units carry the conventionally-known synthetic functional group, while another part carries the proteins.
  • the polymerisation reaction is carried out exactly in the same conditions in which the reaction without replacement is carried out, or in relatively similar conditions.
  • proteins in plastic materials according to the present invention allows bacteria to attack the plastic material, without losing in physical properties, but rather imparting desirable properties, never detected before.
  • the addition of proteins according to the presents invention allows to do without further agents to facilitate the interaction with functional groups, saving raw materials and with an environmental advantage.
  • the individual aminoacids do not have homologous polifunctionality, for example they cannot be used as replacements of polyols because they do not have at least two hydroxylic groups. In order to allow the use of aminoacids, they are reacted with agents which introduce that otherwise missing polifunctionality.
