study of ethylene/vinyl acetate transformation to ethylene/vinyl alcohol copolymer by nmr and dsc
hydrolysis of ethylene-vinyl acetate copolymer in alkaline conditions using two systems of naoh/methanol and koh/isopropanol has been studied and the formation of ethylene-vinyl alcohol copolymer was systematically examined using nmr spectroscopy and dsc measurements. vinyl acetate weight percentage and the degree of hydrolysis were calculated from nmr spectroscopy and it is shown that hydrolys...
متن کاملCharacteristics of ethylene vinyl alcohol copolymer (EVAL) mixtures.
PURPOSE To determine physical characteristics of mixtures of ethylene vinyl alcohol copolymer (EVAL) and metrizamide dissolved in dimethyl sulfoxide, liquid materials developed for embolization of arteriovenous malformations. METHODS EVAL and dimethyl sulfoxide were mixed in various proportions and sterilized. The viscosity and density of each mixture was measured. Precipitation times were de...

OBJECTIVE To review the experience with Onyx embolisation of cerebral arteriovenous malformation. DESIGN Prospective study. SETTING A regional neurosurgical centre in Hong Kong. PATIENTS Data of patients with cerebral arteriovenous malformation who underwent Onyx embolisation over a 14-month period were prospectively collected. RESULTS Eleven sessions of Onyx embolisation were performed...
متن کاملTransarterial embolisation with Guglielmi detachable coils in an infant with a vein of Galen aneurysmal malformation.
Vein of Galen aneurysmal malformation is a rare entity in the paediatric population. However, it is being recognised with increasing frequency due to better diagnostic techniques. Neonates usually present with congestive heart failure, while in older infants and children it tends to manifest with seizures, hydrocephalus, intracerebral or subarachnoid haemorrhages. We present a case of ruptured ...
متن کاملEmbolization of intracranial arteriovenous malformations with ethylene-vinyl alcohol copolymer (Onyx).
BACKGROUND AND PURPOSE Endovascular therapy of intracranial arteriovenous malformations (AVMs) is increasingly used. However, it is still under discussion which embolic material is optimal. We report our experience in the treatment of AVMs with ethylene-vinyl alcohol copolymer (Onyx). MATERIALS AND METHODS Between July 2002 and January 2008, brain AVMs were embolized with Onyx in 82 consecuti...
