This review analyses and summarises the previous investigations on the oxidation of linseed oil and the self-heating of cotton and other materials impregnated with the oil. It discusses the composition and chemical structure of linseed oil, including its drying properties. The review describes several experimental methods used to test the propensity of the oil to induce spontaneous heating and ...

Alkyd resins were prepared into four different sets by varying the percentage concentrationof the glycerol content. Various properties such as the viscosity, Surface drying time, solubilityand color of the alkyd resins were evaluated for the various sets. The alkyd resin with the highestglycerol content was the most viscous, brownish in color and having the highest molecularweight this is due t...

The influence of polluting gases on the stability polymeric films has not been studied extensively. In fact, chemical interactions such materials in contact with ambient atmosphere depend different factors as environmental conditions, manufacturing process product, presence additives or various pigments. this study, accelerated artificial gas ageing was carried out. experiments were performed a...

Microplastic ingestion by lower trophic level organisms is well known, whereas information on microplastic ingestion, egestion and accumulation top predators such as cetaceans still lacking. This study investigates microplastics in intestinal samples from harbour porpoises ( Phocoena phocoena ) found along the coastline of Schleswig-Holstein (Germany) between 2014 2018. Out 30 individuals North...

Like Phenol (C 6 H 5 OH) and Urea {(NH 2 ) 2 C=O)}, Furfuryl alcohol (C 4 H 3 OCH 2 OH), a product of agricultural origin is capable of polymerization with Formaldehyde (H 2 C = 0) under suitable PH conditions. However, usable polymers, at least as no bake for Foundry applications are obtained only when the condensations are carried out in association with Urea, Phenol or both. The series of re...

Ethylene-norbornene copolymers were synthesized with a homogeneous catalyst system based on bis(imino) pyridine iron with the addition of diethyl zinc (DEZ) as alkyd transfer agent to promote immortal copolymerization. The addition of DEZ did not influence the catalytic activity in copolymerization with 7.5 mmol of norbornene (NB), but in the reactions with 70 mmol, the comonomer promoted an in...

Contact: Dr. Charles F. Palmer Ethox Chemicals [email protected] T +1 864 277 1620 They are used in many industrial and architectural applications. The hydrophobic nature of the alkyd polymer makes them good choices when water repellency is important. However, formulating alkyds into low VOC (volatile organic compound) waterborne coatings results in a number of problems, which can be minimised ...
