Several thermostable ordered amide–bithiazole copolymers were prepared by low-temperature solution polycondensation of aromatic diacid chlorides with bis(aminophenyl)bithiazoles. Films were readily prepared from all of these polymers, and a fiber w

The incorporation of more than one dental implant system within the same restorative segment may be a reliable approach to treatment. This article describes a clinical situation that was resolved, after the failure of a pre-existing subperiosteal imp

High-strength/high-modulus polyethylene (PE) fibers have been obtained from linear polymers by melt-spinning the polyethylene followed by hot-drawing the spun filaments. Fibers with different tensile properties were made by changing the extrusion, so

A polyhydrazide was prepared from terephthaldihydrazide (TDH) and terephthaloyl chloride (TCl) and copolyhydrazides from oxalicdihydrazide (ODH) and from TCl with a 50:50 molar mixture of ODH and TDH. The 50:50 copolymer gave superior spinning perfor

Polyethylene (PE) continuous filaments having high tensile strength as well as high Young's modulus have been obtained from several linear polyethylene materials by stretching a partially oriented spun yarn to a draw ratio of ≃30. The high draw rat
