US Patent:

Filed:
May 12, 1994
Appl. No.:
8/241888
Inventors:
Robert J. Duffin - West Chester PA

International Classification:
C09K 2102
C09K 2108
C08K 324
US Classification:
252609
Abstract:
A dehydrated mixture of hydrated sodium antimonate and ionomer polymer flame retard a polymer or resin composition such as film, fiber, electrical connection and molded part. From 10 to 90 parts sodium antimonate containing 3% moisture mixed with 10 to 90 parts ionomer polymer or polyethylene or ethylene vinyl acetate are added to a single screw vented extruder to produce pellet concentrate with a 0. 1% moisture content for flame proofing PET. A composition may be prepared in a single or twin screw extruder or in a high shear blender in the presence of glass fiber by adding a dehydrated mixture of an alkyl tertabromophtalate and sodium antimonate and brominated polystyrene to polyethylene terephthalate or polybutylene terephthalate. A preferred temperature range for dehydration of hydrated sodium antimonate in the presence of a polymer is between 150. degree. C. and 250. degree. C.
