US 10,294,347 B2 · Plasticizer for halogen-based resin

Abstract

The present invention relates to [1] a plasticizer for a halogen-based resin including a condensate obtainable by an esterification reaction between a furan dicarboxylic acid compound and an aliphatic alcohol having 4 to 22 carbon atoms, in which the aliphatic alcohol includes a saturated aliphatic alcohol and an unsaturated aliphatic alcohol, and a content of the unsaturated aliphatic alcohol in the aliphatic alcohol is not more than 25% by mass; and [2] a halogen-based resin composition including the aforementioned plasticizer. The plasticizer has a plasticization performance for a halogen-based resin at a level identical to or higher than that of a phthalate-based plasticizer, and exhibits excellent effects of improving compatibility, heat resistance and cold resistance.

Dependent claims

A plasticizer for a halogen-based resin, the plasticizer comprising a mixture of furan dicarboxylic acid diester represented by the following general formula (1):

wherein R1 and R2 are each independently an aliphatic hydrocarbon group having not less than 4 and not more than 22 carbon atoms, wherein the mixture comprises the diester (i) wherein R1 and R2 are both saturated aliphatic hydrocarbon groups, the diester (ii) wherein one of R1 and R2 is a saturated aliphatic hydrocarbon group and the other of R1 and R2 is an unsaturated aliphatic hydrocarbon group, and the diester (iii) wherein R1 and R2 are both unsaturated aliphatic hydrocarbon groups, provided that a content of the unsaturated aliphatic hydrocarbon groups in R1 and R2 in the diester mixture is not more than 25% by mass in terms of monoalcohol.
