Abstract
A polymer latex for making gloves having excellent donning and doffing characteristics comprises a carboxylated open chain aliphatic diene/acrylonitrile/(meth)acrylate terpolymer. A process for making latex gloves using the polymer latex prepared in accordance with the invention is also disclosed.
Claims15
A latex glove with improved doffing and donning characteristics, wherein said glove is formed from a carboxylated open chain aliphatic diene/acrylonitrile/(meth)acrylate latex polymer comprising about 40 to 80 weight % butadiene, about 15 to 45 weight % acrylonitrile, about 2 to 12 weight (meth)acrylate, and about 2 to 10 weight % of a carboxylic acid or a half ester of a dicarboxylic acid.
In a method for preparing a latex glove comprising:
- (a) contacting a mold resembling a hand with a coagulant;
- (b) removing the mold from the coagulant;
- (c) contacting the coagulant coated mold with a latex for a sufficient period of time to form a gelled latex coating of a desired thickness on the mold;
- (d) drying the latex coated old;
- (e) curing the dried latex coated mold;
- (f) removing the finished cured glove from the mold;
- the improvement which comprises using a latex comprising a carboxylated open chain aliphatic diene/acrylonitrile/(meth)acrylate polymer comprising about 40 to 80 weight % butadiene, about 15 to 45 weight % acrylonitrile, about 2 to 12 weight % (meth)acrylate, and about 2 to 10 weight % of a carboxylic acid.
A method for imparting improved donning and doffing characteristics to a latex glove, comprising forming the glove from a latex composition comprising a carboxylated open chain aliphatic diene/acrylonitrile/(meth)acrylate polymer comprising about 40 to 80 weight % butadiene, about 15 to 45 weight % acrylonitrile, about 2 to 12 weight % (meth)acrylate, and about 2 to 10 weight % of a carboxylic acid or a half ester of a dicarboxylic acid.
