Estimating the term…
A method includes the step of using an aqueous organic peroxide emulsion comprising from 0 to 0.17 wt. % of at least one emulsifier, to prepare polyvinyl chloride with an increased rate of drying. An emulsion includes from 30 to 45 wt. % of diisobutyryl peroxide; from 2.0 to 6.0 wt. % of at least one protective colloid; from 0 to 0.17 wt. % of at least one emulsifier; and at least one anti-freeze agent. A process for preparing a polyvinyl chloride polymer with a normalized drying rate of greater than 0.840 at time t* of 0.5 includes polymerizing monovinyl chloride monomer using an aqueous organic peroxide emulsion, wherein the aqueous organic peroxide emulsion comprises from 0 to 0.17 wt. % emulsifier.
