The industry under consideration uses chiefly the phthalate plasticizers: predominantly dibutyl phthalate (DBP) and higher alkyl phthalates (DAP-789); periodically dioctyl phthalate (DOP), diisooctyl phthalate (DIOP), and benzyl butyl phthalate (BBP). Some formulations contain small amounts of one of the sebacates (dibutyl sebacate, DBS, or dioctyl sebacate, DOS) or adipates (dibutyl adipate, D...

Hot-stage/Fourier transform infrared microspectroscopy (FTIR-M) was used to determine the diffusivities of a series of dialkyl phthalates in poly(viny1 butyral) (PVB) spin-coated films. The diffusivities ranged from lo-'' to lo-'' cmz/s for the isotherms investigated (60" to 150°C). In their respective temperature regimes, dimethyl phthalate and diethyl phthalate exhibited nonlinear diffusion b...

In this article investigates the effect of content plasticizers on properties rubbers based rubber BNKS-18 AMN. The traditional, widely used dioctyl phthalate (DOP), as well more modern, environmentally friendly terephthalate (DOTP), were plasticizers. It has been established that introduction contributes to production with an improved complex operational properties, such elasticity, frost resi...

In this paper, we synthesized a kind of bio-based plasticizer epoxidized linoleic acid cardanol ester (ELCE) from and acid. Its chemical structure was characterized with FT-IR 1H NMR. Polyvinyl chloride (PVC) blends plasticized ELCE were prepared via thermoplastic blending torque rheometer. The performance including torque, mechanical property, thermal stability, plasticizing property migration...

Polyvinyl chloride (PVC) is a very versatile polymer with many applications. Due to the easy incorporation of additives and plasticizers in this resin. The most used plasticizer for PVC dioctyl phthalate (DOP), however its use has been restricted by several organizations because it presents potential toxicity. In way, objective work evaluate thermal, physical dynamic-mechanical characteristics ...

A simple, highly sensitive, accurate and selective method for determination of trace amounts of Ni2+ in water samples. In this paper, Dioctylphthalate (DOP) was used to encapsulate nano-Fe3O4 and produce a nano-Fe3O4-DOP sorbent based new sorbent was prepared. This was treated with ethylenediamine (ED) in another solvent-free procedure for the formation of a novel nano-Fe3O4-DOP-ED. Flame atomi...
