Abstract

Disclosed is a plasticizer comprising xylylene glycol di-2-ethylhexanoate. The plasticizer can comprise xylylene glycol di-2ethylhexanoate and a second plasticizer. Also disclosed is a plastisol comprising a PVC resin dispersed in the liquid phase and a plasticizer comprising xylylene glycol di-2-ethylhexanoate and a second plasticizer. Additionally disclosed, an article can comprise the fused plastisol.

6. The plasticizer of claim 2 comprising about 10 weight percent to about 60 weight percent said xylylene glycol di-2-ethylhexanoate and about 40 weight percent to about 90 weight percent said second plasticizer, each based on the total weight of said plasticizer.

7. The plasticizer of claim 2 comprising about 10 weight percent to about 30 weight percent said xylylene glycol di-2-ethylhexanoate and about 70 weight percent to about 90 weight percent said second plasticizer, each based on the total weight of said plasticizer.

8. A plastisol comprising a plasticizer and a PVC resin dispersed in said plasticizer and wherein said plasticizer comprises xylylene glycol di-2-ethylhexanoate and a second plasticizer.

9. The plastisol of claim 8 wherein said second plasticizer comprises dioctyl terephthalate, diisooctyl phthalate, di-2-ethylhexyl phthalate, di-2-ethylhexyl terephthalate, tri-2-ethylhexyl trimellitate, di-2-propylheptyl phthalate, diisononyl phthalate, diisodecyl phthalate, diisoundecyl phthalate, ditridecyl phthalate, trioctyl trimellitate, triisononyl trimellitate, 2,2,4-trimethyl-1,3-pentanediol diisobutyrate, isononyl benzoate, isodecyl benzoate, diisononyl 1,2-cyclohexanedicarboxylate, dioctyl adipate, di-2-ethylhexyl adipate, triethylene glycol di-2-ethylhexanoate, diethylene glycol dibenzoate, dipropylene glycol dibenzoate, and/or dibenzoates produced from mixtures of diethylene glycol and dipropylene glycol.

10. The plastisol of claim 8 wherein said second plasticizer comprises dioctyl terephthalate, di-2-ethylhexyl terephthalate, dioctyl adipate, di-2-ethylhexyl adipate, and/or triethylene glycol di-2-ethylhexanoate.

11. The plastisol of claim 8 wherein said second plasticizer comprises di-2-ethylhexyl terephthalate, diisononyl phthalate, and/or diisononyl 1,2-cyclohexanedicarboxylate.

12. The plastisol of claim 8 wherein the amount of said plasticizer ranges from about 20 parts to about 800 parts per 100 parts of said PVC resin.
