Definitions

  • Plasticized polyvinyl butyrals processes for their production and their use, in particular for the production of films for use in laminated safety glasses
  • the present invention relates to plasticized polyvinyl butyrals, processes for their preparation and their use in any molding compositions, in particular for the production of foils, which can be used, for example, as an intermediate layer in laminated safety glasses.
  • PVB polyvinyl butyral
  • VSG laminated safety glass
  • Plasticizers suitable for the production of PVB films must meet certain requirements. Important properties include very good compatibility with PVB, high transparency (colorless, cloud-free), a high boiling point and a low moisture content as well as high hydrophobicity.
  • plasticizers for PVB are the esters of aliphatic mono- and dicarboxylic acids with mono- or polyhydric alcohols or oligoalkylene glycol ethers, and various phthalates, as are disclosed, for example, in US Pat. No. 5,137,954.
  • the diesters of di-, tri- and tetraethylene glycols with aliphatic monocarboxylic acids and dialkyl adipate are preferably used.
  • triethylene glycol di-2-ethylhexanoate is particularly preferably used as the plasticizer, the use of which is disclosed, for example, in DE-A-24 53 780 and WO 97/24230.
  • plasticizer triethylene glycol di-2-ethylhexanoate has the disadvantage that it is only well tolerated with polyvinyl butyral, which has polyvinyl alcohol contents (PVA contents) of less than 19.5% by weight.
  • Dibenzoates of di- and trialkylene glycols e.g. are known from US-A-2,956,978, are disclosed in DE-A-28 20 780 as a possible component of a special plasticizer mixture for PVB which contains phosphoric acid esters.
  • the object of the present invention was therefore to provide plasticizers for plasticizing PVB which have very good compatibility with PVB, in particular also with more hydrophilic polyvinyl butyrals with higher polyvinyl alcohol contents.
  • the plasticizers should be cheaper than the known plasticizers for PVB.
  • dibenzoates of alkylene and / or polyalkylene glycols in particular di-, tri- and / or tetraalkylene glycols, solve the above-mentioned task and fulfill the requirements placed on them as plasticizers for plasticizing PVB much better than those for the plasticization of PVB compounds normally used.
  • the present invention thus relates to plasticized polyvinyl butyrals which are characterized in that they contain at least one dibenzoate of alkylene and / or polyalkylene glycols as plasticizer.
  • Preferred plasticizers are dibenzoates of di-, tri- and tetraalkylene glycols, the dibenzoates of the dialkylene glycols being particularly preferred and here in particular the dipropylene glycol dibenzoate.
  • the dibenzoate plasticizers can also contain the corresponding monobenzoates. They can also contain the benzoic acid esters of the corresponding monoalkylene glycols.
  • plasticizers used according to the invention are distinguished by a considerably better compatibility with the polyvinyl butyral.
  • Compatibility manifests itself in comparison with the prior art in minimizing the undesirable exudation phenomena.
  • the ratio of hydrophilic and hydrophobic molecular components - the so-called HLB value (hydrophilic / lipophilic balance) - is comparable to the alkylene glycol diests known for PVB film production, which also include triethylene glycol di-2-ethylhexanoate.
  • the polyvinyl alcohol contents of the polyvinyl butyrals used as starting materials are preferably between 10 and 25% by weight, particularly preferably between 16 and 23% by weight.
  • the polyvinyl butyrals used are in no way restricted. However, polyvinyl butyrals with a molecular weight of at least 50,000 g / mol are preferably used.
  • the polyvinyl acetate contents of the polyvinyl butyrals used as starting materials are preferably between 0 and 20% by weight.
  • 100 g DHA and 50 g DPGDB are used.
  • Examples 6 and 7 show that mixtures of DPGDB with other plasticizers are also suitable for the production of PVB films for laminated safety glass (see Table 5).
