Vinsol

A change in the supply situation of Vinsol resin with a commensurate price increase as well as the more widespread use of supplementary materials led almost all admixture companies to reformulate their air-entraining agents using synthetic or alternative natural products such as tall oil or rosins. In a period of about 2 years, a product that had been in dominant use for 40 years was relegated to a lesser role in the industry. 

Neutralized vinsol resin, sulfonated hydrocarbon, and fatty-acid (detergent)-based AEAs give satisfactory AVSs, but at low dosages, only synthetic detergent-based materials can produce an adequate and stable spacing factor. 

Although they are a relatively small volume product—approximately 75,000 tons produced in 1949 (126)—interest in asphalt emulsion has continued at a high level. Abraham (6) has reviewed the patent literature relative to the types of emulsifying agents used, while commercial practice has been discussed by Day (16). The most common emulsifiers are sodium or potassium soaps of tall oil, abietic acid, or Vinsol resin, or colloidal clays such as bentonite for adhesive base emulsions. Lyttleton and Traxler (53) studied the flow properties of asphalt emulsions, and Traxler (122) has investigated the effect of size distribution of the dispersed particles on emulsion viscosity. A decrease in particle size uniformity was found to be accompanied by a decrease in consistency because particles of various size assume a more loosely packed condition than do those of the same size.

There are several materials that make up this category, including wood-derived tall oil rosins and pine stump extracts sold under the well known Vinsol trade mark. They consist of complicated mixtures containing greater or lesser amounts of abietic acid (Fig 3.2) together with pimaric add, and phenolic compounds such as phlobaphenes. 

Butyl ricinoleate, is a plasticizer for polyvinyl butyral, rosin, vinsol resin, and cellulose acetate butyrate resins. Can also be used as a general purpose plasticizer for both nitrocellulose and ethylcellulose.
