1. 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, wherein the one or more chalcogenic monomers comprise sulfur and selenium;
ii. a comonomer at a level in the range of about 5-55 wt % of the CHIP material, wherein the comonomer is co-polymerized with the one or more chalcogenic monomers; and
iii. a termonomer at a level in the range of about 5-45 wt % of the CHIP material, wherein the termonomer is co-polymerized with the one or more chalcogenic monomers and the comonomer, wherein the termonomer is different from the comonomer;
wherein the comonomer improves miscibility of the vulcanizing agent, wherein the vulcanizing agent allows for a higher crosslinking efficiency vulcanization than elemental sulfur,
wherein the vulcanizing agent vulcanizes the latex material to provide a crosslinked rubber.
