Abstract
Low VOC viscosity reducer (LVVR) compounds useful for reducing the viscosity of plastisol compositions. The plastisol compositions are combined with a viscosity reducing compound which is derived from the reaction of at least one of 2,2,4-trimethyl-1,3-pentane diol (TMPD) and 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate (TXOL) with at least one of a carboxylic acid or a fatty acid.
Claims28
A polyvinyichloride plastisol composition comprising a polyvinyichloride resin, a plasticizer, and a viscosity reducing compound, wherein said compound is represented by the following structure:
- wherein a total number of carbons represented by R1 and R2 is between about 9 carbons and 20 carbons.
A polyvinylchloride plastisol composition comprising a polyvinylchloride resin, a plasticizer, and a viscosity reducing compound, wherein said compound is a diester derived from the reaction of:
- a) at least one of 2,2,4-trimethyl-1,3-pentane diol (TMPD) and 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate (TXOL);
- and
- b) an alkyl carboxylic acid, a fatty acid, or a mixture thereof, wherein the carboxylic acid or fatty acid consists of 8-20 carbon atoms.
A method of producing a polyvinyl chloride (PVC) plastisol composition having a reduced viscosity comprising contacting the plastisol composition and a viscosity reducing compound, wherein said compound is represented by the following structure:
- wherein a total number of carbons represented by R1 and R2 is between about 9 carbons and 20 carbons.
A method of producing a polyvinylchloride plastisol composition having a reduced viscosity comprising contacting:
- a) a polyvinylchloride plastisol;
- and
- b) a viscosity reducing compound wherein said compound is a diester derived from the reaction of:
- i) at least one of 2,2,4-trimethyl-1,3-pentane diol (TMPD) and 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate (TXOL);
- and
- ii) an alkyl carboxylic acid, a fatty acid, or a mixture thereof,
- wherein the carboxylic acid or fatty acid consists of all isomers of 8-20 carbon atoms.
