К числу таких характеристик можно отнести высокую термоста- бильность в условиях гидростатических и гидродинамических нагрузок, а также механические и диффузи- онные свойства. Особенностью PERT является то, что необходимая прочность при высоких температу- рах достигается без необходимости в сшивке макромолекул, благодаря уникальной кристаллической структуре этих материалов. С учетом его универсальности полиэтилен PERT рекомендуется при произ- водстве труб, предназначенных для горячего водоснабжения и отопительных систем.</p></abstract><trans-abstract xml:lang="en"><p>This article discusses a new class of ethylene-α-olefin copolymers known as PERT (polyethylene with enhanced temperature stability), which exhibit improved physical and chemical properties. These properties include high thermal stability under hydrostatic and hydrodynamic loads, as well as mechanical and diffusion prop- erties. A special feature of PERT is that the required strength at high temperatures is achieved without the need for cross-linking of macromolecules, due to the unique crystalline structure of these materials. Given its versatility, polyethylene PERT is recommended for the production of pipes intended for hot water supply and heating systems.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Линейный полиэтилен</kwd><kwd>сомономер</kwd><kwd>полиэтилен высокой плотности (ПЭВП)</kwd><kwd>сополимер этилена-α-олефина PERT.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>linear polyethylene</kwd><kwd>co-monomer</kwd><kwd>high-density polyethylene (HDPE)</kwd><kwd>ethylene-α-olefin co- polymer</kwd><kwd>PERT.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Куликовская К.А., Водяков В.Н., Шабарин А.А.
