1. fatty acid esters the low temperature performance of fatty acid esters is very good, but their miscibility with pvc is poor, so they can only be used as cold resistant by plasticizer and phthalate esters. the most commonly used varieties are dioctyl adipate and
effective, environmentally friendly pvc plasticizers based on succinic,the plasticizers used in this study were synthesized from renewable raw materials using succinic acid, oleic acid, and propylene glycol. four environmentally friendly plasticizer samples were obtained; their chemical structures and compositions were confirmed.

end-capped biobased saturated polyesters as effective plasticizers for pvc,in this work, novel linear sps were prepared by bulk polycondensation, end-capped with alcohols with branched and linear structures and used as plasticizers for pvc. it was hypothesized that end-capping the sps with alcohols with longer alkyl chains (viz. 2-tetradecyloctadecan-1-ol (tdod) and octanol (oc) (c n > 1)) would, in one hand, improve the interactions with pvc and, on the other hand.
but citrate plasticizers can only be used in pvc articles because of their low boiling points, high volatility, inferior heat tolerance, ease of aging, and high cost. epoxy plant oil plasticizers, including epoxy soybean oil, epoxy linseed oil, etc. can improve the anti26

molecules 2021, 26, 1221 3 of 17 detailed structural characterization of small molecules and reaction monitoring [44,46]. the application of low-field nmr spectroscopy for the study of larger and more complex molecules has started more recently. this is because
role of different plasticizers in pvc products chemical plasticizer,if plasticizer is too polar, it can destroy crystallites, on the other hand, too non polar plasticizer will cause compatibility problem in pvc. an ideal plasticizer should be – cost effective.

therefore, several attempts have been made to develop new compounds that might act as plasticizers in pvc formulations. so far, researchers have been investigating bio-based compounds, branched.
diisobutyl phthalate an overview plasticizer chemical,diisobutyl phthalate is a liquid compound with the iupac name 2-methylpropyl 2-[(2-methylpropyl)oxycarbonyl]benzoate, commonly used in polymers like pvc and pvac, as well as in products such as cables and shoes. ai generated definition based on: plasticizers databook, 2013
