Determination of Polymer Additives

Among a wide variety of polymer additives present in plastic antioxidants UV stabilizers plasticizers and photoinitiators are widely used Antioxidants are both natural and synthetic compounds able to scavenge free radical and to inhibit oxidation process UV stabilizers can absorb most of the UV-light and reduce the UV-light absorption of polymer matrix In addition phthalate acid esters

PVC

polymer matrix This is typically obtained by heating and mixing until either the resin dissolves in the plasticizer or the plasticizer dissolves in the resin The plasticized material is then molded or shaped into the useful product and cooled Different plasticizers will exhibit different characteristics in both the ease with which they form the plasticized material and in the resulting

Final Report

Plasticizers are not directly bound to the polymer chain and can escape from the plasticized material Loss of plasticizers is an undesirable event leading to brittle and unusable materials and contamination of the surrounding environment This is particularly a problem for polyvinyl chloride (PVC) which can be highly plasticized and often is used in toys for infants and medical tubing and

Green Plasticizers for PVC

Recent researches have established that phthalate plasticizers have a tendency to migrate from a polymer matrix into which it has been incorporated into the natural environment Consequently ecological exposure has become eminent where for humans it has been associated with several diseases Therefore efforts to find a suitable replacement have picked up the pace

Accelerated Solvent Extraction for Additivies in Polymer

These polymer additives were extracted using approximately 30 mL of solvent with an extraction time of 20 min per sample The extracts analyzed using HPLC with UV detection and the additives were resolved in 18 min using a C18 column Cellulose extraction thimbles were used to prevent plugging of the extraction cell and enable extraction of the polymeric components at elevated temerature and

Hidden Hazards

Polymer clays are a form of modeling clay that have become popular in recent years among children adolescents and adult craftspeople Unfortunately these clays contain polyvinyl chloride (PVC) mixed with phthalate plasticizers While the phthalate plasticizers make the clay soft and workable they are also associated with potential health risks

Effects of Graphite and Plasticizers on the Structure of

Using a simple and efficient way to optimize a chemically specific bead-and-spring model for polymer/surface systems we analyze the structural properties of high molecular weight polyisoprene (PI) in contact with graphite We find that in the vicinity of the graphite the adsorbed PI chains assume a pancake structure and are highly packed and highly entangled The addition of plasticizers even

Plasticizer

Plasticizers are low molecular weight substances added to a polymer solution to promote its plasticity and flexibility Therefore the plasticizers make the polymer solution more suitable for the application of film coating There should be chemical similarities between the polymers and its plasticizers It is supposed that the function of the plasticizer is that its molecules are embedded
