Plastisols and organosols are provided that include plasticizers that include mono-, di- and triesters of glycerol. The plasticizers are good solvators for polyvinyl chloride and impart low plastisol and organosol viscosities.
Claims8
A method for making a polymer composition, the method comprising;
- dispersing particles of organic polymer to form a polymer dispersion;
- and
- blending glycerol ester with the polymer in an amount effective for plasticizing the polymer, wherein the glycerol ester is selected from the group consisting of mono-, di- and triesters of glycerol, and mixtures thereof, the glycerol esters having a general formula
- wherein 0 to 2 X groups are hydroxyl and 1 to 3 X groups are
- wherein R1 is —(CH2)n—CH3, where n is 0 to 5,
- wherein all R1 groups are identical,
- and wherein if n is 0, then 1 to 2 X groups are hydroxyl.
