Abstract
Methods of vulcanization using a high content sulfur polymer, instead of elemental sulfur, have been developed. These high sulfur content polymers are referred to as Chalcogenide Hybrid Inorganic/Organic Polymers (CHIP) materials and have good polymer compatibility in that they are soluble in a number of polymers. Furthermore, CHIP materials may have weaker bonds than the S—S bonds of elemental sulfur and thus provide for a higher crosslinking efficiency vulcanization.
Claims26
A composition comprising:
- a. a latex material;
- and
- b. a vulcanizing agent comprising a chalcogenic hybrid inorganic/organic polymer (CHIP) material, wherein the CHIP material comprises:
- i. one or more chalcogenic monomers at a level of at least 45 wt % of the CHIP material;
- and
- ii. one or more comonomers, at a level in the range of about 5-55 wt % of the CHIP material, wherein the one or more comonomers are co-polymerized with the chalcogenic monomers;
- iii. one or more termonomers, at a level in the range of about 5-45 wt % of the CHIP material, wherein the one or more comonomers are co-polymerized with the chalcogenic monomers and the one or more comonomers;
- wherein the vulcanizing agent vulcanizes the latex material to provide a crosslinked rubber.
