VULCANIZATION SYSTEMS FOR CURING BLOCK COPOLYMER LATEX FILMS |
| 摘要 |
A method for the curing of aqueous latexes comprising block copolymers is disclosed. The block copolymers have the general formula A-B-A or A-B-Y-(B-A)n. The curing is conducted using vulcanization systems that are free of guanidine and thiuram compounds. The cured latexes are useful in the manufacture of elastic films, surgical, examination and electrical insulation gloves, industrial gloves and condoms. |
