Possibilities of polyamide 12 with poly(vinyl chloride) blends recycling

Abstract

Possibilities of polyamide 12 with poly(vinyl chloride) blends recycling Summary-Blends of poly(vinyl chloride) (PVC) and polyamide 12 (PA 12) were prepared by melt mixing technique in Brabender Plastograph. The samples have been studied by scanning electron microscopy (SEM), dynamic mechanical analysis (DMA), differential scanning calorimetry (DSC) and Charpy impact strength was tested. PVC/PA 12 blends were compatibilized with chlorinated polyethylene (CPE) and investigeted using the same methods. It was shown that such compatibilization is one of the possibilities how to get desired properties starting from brittle and immiscible PVC/PA 12 blends. Key words-poly(vinyl chloride), polyamide, compatibilization, blend. MO¯LIWOOECI RECYKLINGU MIESZANEK POLI(CHLOREK WINYLU)/POLIAMID 12 Streszczenie-Za pomoc¹ plastografu Brabendera przygotowano mieszanki poli(chlorku winylu) (PVC) i poliamidu 12 (PA 12). Otrzymane próbki badano metodami skaningowej mikroskopii elektronowej (SEM) (rys. 2), dynamicznej analizy mechanicznej (DMA) (rys. 3, tabela 1), skaningowej kalorymetrii ró¿nicowej (DSC) (tabela 1) oraz wyznaczono udarnooeae metod¹ Charpy'ego (rys. 1). Za pomoc¹ tych samych metod zbadano zdolnooeae mieszanek PVC/PA 12 do kompatybilizacji za pomoc¹ chlorowanego polietylenu (CPE) (rys. 4-17). Otrzymane wyniki potwierdzi³y mo¿liwooeci uzyskania z kruchych i niemieszalnych uk³adów PVC/PA 12 mieszanek o po¿¹danych w³aoeciwooeciach. S³owa kluczowe: poli(chlorek winylu), poliamid, kompatybilizacja, mieszanina.

Properties of poly(vinyl chloride) and polyesteramides blends

“…To modify the properties of PVC, polyamides or polyesteramides (based on ε‐caprolactone and lactams) can also be used 7–10. Poly[(ω‐laurolactam)‐ block ‐(ε‐caprolactone)] has successfully been applied as a compatibilizer of the PVC‐polyamide 12 blends or the PVC/PP blends 8, 9.…”
