Determination of the plasticizer content in poly(vinyl ...

The effects of the ageing trials in the plasticizer content of the test specimens can be determined by calculating the plasticizer to IS ratio. The bar charts presented in Fig. 3 , Fig. 4 illustrate the results obtained after 48 and 96 h of exposition in the UV-light artificial ageing chamber, for DEP and DBP, respectively.

A new method consisting of the quantification of the plasticizer content of PVAc samples with “on-line” silylation–pyrolysis with hexadimethyldisilazane (HMDS) as a derivatization agent in Py–GC–MS and using 1,4-dibromebenzene as an IS is proposed here.

Determination of the plasticizer content in poly(vinyl ...

The use of plasticizers in emulsion paints is intended to provide optimal mechanical properties to polyvinyl acetate polymers (PVA), making them suitable as binding media for paintings. The loss of these properties with ageing is often related to the slow migration and evaporation of such plasticizers, resulting in severe embrittlement and potential damage to the paint film.

Medical devices (MDs) for infusion and enteral and parenteral nutrition are essentially made of plasticized polyvinyl chloride (PVC). The first step in assessing patient exposure to these plasticizers, as well as ensuring that the MDs are free from di(2-ethylhexyl) phthalate (DEHP), consists of identifying and quantifying the plasticizers present and, consequently, determining which ones are ...
