ABSTRACT OF THE DISCLOSURE 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 reten-tion of their original adhesive properties. These graft modified oils, also, can be used as seeds or emulsifiers, when emulsified, in emulsion polymeriza-tion. These grafted oils can be used as plasticizers for plastics and dry rubbers. |
