Effect of Copoly(Ester-Amide 6)(PET-PA6) on Compatibility of PET/PA6 Blended Fibers

Autor: Jin Long Xu, Guang Li, Song Lin Wang, Yu Kun Shi, Jun Hong Jin, Sheng Lin Yang

Publikováno v: Materials Science Forum. 993:709-717

Significant improvement of compatibility in PET/PA6 blends is essential to obtain fibers having enough mechanical strength as well as the comprehensive performance. In this article, copoly (ester-amide 6) was used as compatibilizer to improve the com

The early Paleozoic sediments document two major biological events: the Great Ordovician Biodiversification Event (GOBE) and Late Ordovician mass extinction (LOME). Many investigations have focused on taxonomic richness patterns during these major di

Publikováno v: Earth-Science Reviews. 220:103699

The Late Paleozoic Ice Age (LPIA) is a critical interval for marine ecosystems when marine fauna was viewed to have experienced a second-order mass extinction and a “sluggish” evolution with low origination and extinction rates. However, our rece

The Permian Period is punctuated by Earth system changes unlike any other in geological history. The start of the Permian witnessed the termination of the Late Paleozoic Ice Age, followed by the climatic transition from icehouse to greenhouse conditi

The Cimmerian continent is composed of a series of blocks that were attached to the northern margin of Gondwana during the Carboniferous-Permian time, and as a consequence therefore, developed glacial sediments during the Late Paleozoic Ice Age (LPIA

Climatic warming has been widely cited as a driver for many mass extinction events in Earth history, including the middle-late Permian Guadalupian-Lopingian boundary (GLB) mass extinction and end-Permian mass extinction (EPME) investigated in this st
