Abstract

Plasticizers of glycol ether-based cyclohexanoate esters and blends thereof with thermoplastic polymers, such as PVC, are disclosed.

First claim

What is claimed is:

1. A composition comprising a thermoplastic polymer and a first plasticizer compound of the formula:

wherein each R 1 is, independently, C 1 to C 12 linear or branched alkyl; each R 2 is, independently, H or CH 3 ; each n is, independently, 1, 2, 3 or 4, and when n=4, R 1 is C 2 to C 12 linear or branched alkyl,
wherein the composition further comprises a second plasticizer comprising a compound of the formula:

wherein R* 1 is a saturated or unsaturated cyclic hydrocarbon substituted with an alkyl and/or an OXO-ester, and R* 2 is a C 4 to C 20 hydrocarbyl, and wherein the second plasticizer compound comprises at least two cyclic moieties directly bonded to each other.

2. The composition of claim 1 , wherein each R 1 is independently, C 2 to C 6 alkyl.

3. The composition of claim 1 , wherein each R 1 is independently, C 1 to C 6 alkyl, R 2 is H, and n is 2 or 3.

4. The composition of claim 1 , wherein R 1 is C 1 to C 6 alkyl, R 2 is CH 3 , and n is 2 or 3.

5. The composition of claim 1 , wherein R 1 is C 2 to C 12 alkyl, R 2 is H, and n is 4.

6. The composition of claim 1 , where the first plasticizer compound is represented by one or more of the following formulae:

7. The composition of claim 1 , wherein the thermoplastic polymer comprises at least one of vinyl chloride resins, polyesters, polyurethanes, ethylene-vinyl acetate copolymer, rubbers, poly(meth)acrylics and combinations thereof.

8. The composition of claim 1 , wherein the thermoplastic polymer is polyvinyl chloride.

9. The composition of claim 1 , wherein the thermoplastic polymer is present at 99 to 40 wt % and the first plasticizer is present at 1 to 60 wt %.

10. The composition of claim 1 , wherein the thermoplastic polymer is a PVC suspension, a PVC microsuspension, a PVC emulsion, or a combination thereof.

11. The polymer composition of claim 1 , further comprising: an additive of at least one of a filler, a pigment, a matting agent, a heat stabilizer, an antioxidant, a UV stabilizer, a flame retardant, a viscosity regulator, a solvent, a deaerating agent, an adhesion promoter, a process aid, and a lubricant.

12. A floor covering, wallpaper, tarpaulin, coated textile, wall covering comprising the composition of claim 1 .

13. A film comprising the composition of claim 1 wherein the film is a roofing sheet, a tarpaulin, a banner, synthetic leather, packaging film, a medical article, a toy, a seal, or an automobile interior article.

14. The composition of claim 1 , wherein the first plasticizer is one or more of:
di(ethylene glycol)monohexyl cyclohexane-1,2-dicarboxylate,
tri(ethylene glycol)monomethyl cyclohexane-1,2-dicarboxylate,
tri(propylene glycol)monomethyl cyclohexane-1,2-dicarboxylate,
tri(ethylene glycol)monoethyl cyclohexane-1,2-dicarboxylate,
tri(ethylene glycol)monobutyl cyclohexane-1,2-dicarboxylate,
di(ethylene glycol)monoethyl cyclohexane-1,2-dicarboxylate,
di(ethylene glycol)monobutyl cyclohexane-1,2-dicarboxylate,
tri(propylene glycol)monopropyl cyclohexane-1,2-dicarboxylate,
tri(propylene glycol)monobutyl cyclohexane-1,2-dicarboxylate,
poly(ethylene glycol)(4)dodecyl cyclohexane-1,2-dicarboxylate,
ethylene glycol mono-2-ethylhexyl cyclohexane-1,2-dicarboxylate,
tetra(ethylene glycol) mono methyl cyclohexane-1,2-dicarboxylate,
di(ethylene glycol)hexadecyl cyclohexane-1,2-dicarboxylate,
di(ethylene glycol)octadecyl cyclohexane-1,2-dicarboxylate,
propylene glycol butyl cyclohexane-1,2-dicarboxylate, and
di(propylene glycol)methyl cyclohexane-1,2-dicarboxylate.
