Abstract
Způsob zdravotně nezávadné stabilizace polyolefinů proti ternicoxidační a fotooxi- dační degradaci, při kterém se jako stabilizátoru použije lalfa-tokoferolu, beta-tokofero- lu, gama-tokoferolu, delta-tokoferolu nebo jejich směsi.A process for the safe stabilization of polyolefins against ternoxidative and photooxidative degradation, wherein lapha-tocopherol, beta-tocopherol, gamma-tocopherol, delta-tocopherol or a mixture thereof is used as a stabilizer.
Description
Vynález se týká způsobu stabilizace polyolefinů, kterým se dosahuje zvýšení odolnosti proti termooxidačnímu a fotooxidačnímu stárnutí, přičemž polyolefiny stabilizované podle vynálezu jsou zdravotně nezávadné.The present invention relates to a process for stabilizing polyolefins by means of which the resistance to thermooxidation and photooxidation aging is increased, the polyolefins stabilized according to the invention being wholesome.
Dosavadní způsob stabilizace polyolefinů proti termooxidační degradaci a proti fotooxidační degradaci se provádí aplikací antioxidamtů, které jsou odvozeny z derivátů fenolů, aromatických aminů, fosfitů. Tyto látky jsou většinou zdravotně závadné a nelze je použít ve styku s potravinami. Polyolefiny stabilizované těmito látkami vyvolávají nežádoucí zánětlivé procesy, jestliže jsou použity jako implantáty ve styku s tkáněmi organismu. U některých z těchto sloučenin byl zjištěn karcinogenní účinek (například u f enyl-beta-naf tylaminu j.The prior art method of stabilizing polyolefins against thermooxidative degradation and photooxidative degradation is accomplished by applying antioxidants derived from phenol derivatives, aromatic amines, phosphites. These substances are mostly harmful to health and cannot be used in contact with food. Polyolefins stabilized by these substances induce unwanted inflammatory processes when used as implants in contact with body tissues. Some of these compounds have been found to be carcinogenic (e.g., phenyl-beta-naphthylamine).
Výše uvedené nedostatky jsou odstraněny stabilizací polyolefinů podle vynálezu, jejíž podstatou je aplikace 0,01 až 5 % alfa-tokoferolu, beta-tokořerolu, gama-tokoferolu, delta-tokoferolu nebo jejich směsi do polyolefinů.The above drawbacks are overcome by stabilizing the polyolefins according to the invention, which is based on the application of 0.01-5% alpha-tocopherol, beta-tocopherol, gamma-tocopherol, delta-tocopherol or a mixture thereof into polyolefins.
Polyolefiny stabilizované tokoferolem mají podstatně větší odolnost proti termooxidační degradaci jak při teplotách technického použití těchto materiálů, tak při teplotách zpracovatelských. Mají vyšší odolnost proti fotooxidační degradaci, která se projevuje vyšší životností při expozici polyPlefinů stabilizovaných tokoferolem v přírodních povětrnostních podmínkách. Jsou zdravotně nezávadné. Lze je použít ve styku s potravinami. Nevyvolávají nepříznivé reakce tkání, jestliže jsou takto stabilizované polyolefiny použity jako implantáty v organismu. Mají naopak příznivý vliv na vhojovací procesy.The tocopherol-stabilized polyolefins have significantly greater resistance to thermo-oxidative degradation at both the technical and processing temperatures of these materials. They have a higher resistance to photooxidative degradation, which results in higher durability when exposed to tocopherol-stabilized polyPlefin under natural weather conditions. They are harmless to health. They can be used in contact with food. They do not induce adverse tissue responses when such stabilized polyolefins are used as implants in the body. On the contrary, they have a beneficial effect on healing processes.
