Abstract
Abstract Free-radical graft polymerization of an unsaturated monomer like acrylic acid, methacrylic acid and so forth on mineral oils such as rubber processing and/or extending oils provides a "grafted oil" which can be used to extend polymers such as carboxylated SBR latices with substantial retention of their original adhesive properties. These grafted modified oils, also, can be used as seeds or emulsifiers, when emulsified, in emulsion polymerization. These grafted oils can be used as plasticizers for plastics and dry rubbers.
