Disclosed is a heat curable solvent free plastisol composition that exhibits very low volatile organic compound amounts while maintaining high performance characteristics. The present plastisol compositions have solvent substitutes used at amounts up to 15% by weight based on the total composition weight. The solvent substitutes have very low vapor pressures, stable viscosity effects, and are fusible with the plastisol polymers. These solvent substitutes can be used to replace the typical solvents without requiring extensive re-formulation of the plastisol composition. The final plastisol compositions according to the present invention exhibit low VOC measures of less than 0.03 pounds per gallon when measured according to EPA Method 24.

A method for producing a vinyl chloride type polymer is to produce the vinyl chloride type polymer by polymerizing a vinyl chloride monomer, or a mixture of a vinyl chloride monomer with a monomer copolymerizable with the vinyl chloride monomer in an aqueous medium by using a polymerization reactor. An aqueous solution of a copolymerized polyether having a weight-average molecular weight of 1,000 to 3,500 with a mole ratio of ethylene oxide to propylene oxide in the range of 10/90 to 60/40 is charged into the polymerization reactor with an amount of 0.005 to 0.050 part by weight as the copolymerized polyether relative to 100 parts by weight of the vinyl chloride monomer.

A method of reducing foamed density that results in a foamed polyvinyl chloride (PVC) component exhibiting reduced density. The foamed PVC component contains at least a PVC resin and a process aid blend. The process aid blend contains from 1 weight % to 60 weight % (based on the weight of the blend) of a functionalized process aid, and from 99 weight % to 40 weight % (based on the weight of the blend) of a non-functionalized process aid. The functionalized process aid includes at least one base polymer functionalized with a reactive epoxy, hydroxyl, β-keto ester, β-keto amide, or carboxylic acid functional group. The foamed PVC component containing the process aid blend has a lower density than a reference foamed PVC component made using the same process conditions and additives, but which contains only non-functionalized process aid and not the functionalized process aid.
