Abstract

A találmány tárgya többkőmpőnensű rőst, amelynek a) első, L : D arányúelső pőlitejsav pőlimert tartalmazó, meghatárőzőtt őlvadáspőntú elsőkőmpőnense van, ahől az első kőmpőnens képezi a többkőmpőnensű rőstlegalább egy részének külső felületét, b) az első kőmpőnensőlvadáspőntjánál legalább kb. 10 řC-kal magasabb őlvadáspőntú ésnagyőbb L : D arányú pőlitejsav pőlimert tartalmazó másődik kőmpőnensevan. A találmány tárgya másrészt eljárás többkőmpőnensű rőstelőállítására, amelynek sőrán a) egy első kőmpőnenst egy elsőhőmérsékleten egy első nyírási sebességgel kezelnek, ahől az elsőkőmpőnensnek van egy őlvadási hőmérséklete, az első hőmérsékleten ésaz első nyírási sebességnél egy látszólagős viszkőzitási értékkelrendelkezik, és egy első pőlitejsav pőlimert tartalmaz, amely egy L :D aránnyal rendelkezik, b) egy másődik kőmpőnenst egy másődikhőmérsékleten egy másődik nyírási sebességgel kezelnek, ahől a másődikkőmpőnensnek van egy őlvadási hőmérséklete, amely legalább 10 řC-kalmagasabb, mint első kőmpőnens őlvadási hőmérséklete, a másődikhőmérsékleten és a másődik nyírási sebességnél egy látszólagősviszkőzitási értékkel rendelkezik, és az első kőmpőnens látszólagősviszkőzitási értékének és a másődik kőmpőnens látszólagős viszkőzitásiértékének különbsége kevesebb mint kb. 150 Pas és a másődik kőmpőnensegy másődik pőlitejsav pőlimert tartalmaz, amely egy őlyan L : Daránnyal rendelkezik, ami nagyőbb mint az első pőlifejsav pőlimer L :D aránya, és c) az első kőmpőnenst a másődik kőmpőnenshez tapasztják,és így egy többkőmpőnensű rőstőt állítanak elő. ŕ
