LIGHT PROTECTIVE ADDITIVE BASED ON ORGANIC/ INORGANIC HYBRID POLYMER, METHOD FOR ITS MANUFACTURE AND USE THEREOF

摘要

Ligh protective additive based on a polybranched organic/ inorganic hybrid polymer manufactured by a sol-gel process as well as method for its manufacture, having a chemical basic structure: Formula (I), R₁- R₄ are chosen among groups such as hydrogen, unsubstituted saturated or unsaturated C₁-C₂₄ alkyl, substituted saturated or unsaturated alkyl, substituted or unsubstituted aryl, halogen, hydroxyl, substituted or unsubstituted amine, aliphatic or aromatic carbonyl, or where R₁-R₄ are chosen among the condensation products or addition products of one or more types of chemical compositions such as acids, alcohols, phenols, amines, aldehydes, or epoxides. The groups R₁-R₄ can form substituted or unsubstituted aromatic ring structures that together with the existing aromatic ring constitute a larger ring structure than phenyl, while M, Z are chosen among the elements oxygen, nitrogen, and sulphur. The invention furthermore concerns use of such an additive and thermoplastic material comprising such additive as well as products thereof.
