  • Plasticizers Production and Use
    Publication number: 20170253724
    Abstract: This disclosure relates to blends of aromatic ester plasticizers. The plasticizer blends include a first group of one or more methyl biphenyl carboxylic acid esters of C7 to C13 alcohol and a second group of methyl biphenyl carboxylic acid esters of C4 to C6 alcohol. The disclosure further relates to polymer compositions comprising the plasticizers and thermoplastic polymer, such as polyvinylchloride.

  • Plasticizer blends and use thereof
    Patent number: 9534104
    Abstract: Provided are mixtures of 1) compounds of the formula: wherein R1 is a saturated or unsaturated cyclic hydrocarbon optionally substituted with an alkyl and/or an OXO-ester, and R2 is a C4 to C14 hydrocarbyl; and 2) one or more second plasticizers selected from the group consisting of alkyl terephthalates, alkyl phthalates, alkyl benzoate esters, di-benzoate esters, esters of cyclohexane polycarboxylic acids, and dialkyl adipates. Also provided are plasticized polymer compositions containing said mixtures.
