Abstract
The present invention is directed to methods of making natural or synthetic latex articles without the use of accelerators, thiurams or carbamates. The method includes making an elastomeric material by mixing a base polymer containing carboxylate groups with a carboxylic acid or derivative thereof, a divalent or trivalent metal, an amine or amino compound, and a neutralizing agent. The elastomeric material is formed into a latex article. The present invention is also directed to a latex article made according to this method. The latex article does not contain any accelerators, thiurams or carbamates.
Claims7
An elastomeric material comprising:
- a base polymer;
- a carboxylic acid or a derivative thereof;
- a compound including a divalent or trivalent metal;
- an amine or amino compound;
- and
- a neutralizing agent to neutralize at least a portion of the carboxylate groups in the base polymer;
- wherein the carboxylic acid or derivative thereof provides a level of carboxyl groups sufficient to crosslink with the base polymer and to complex with the divalent or trivalent metal, and wherein the elastomeric material does not comprise an accelerator, thiuram or carbamate.
