Claims23
A composition comprising compounds of Formula (I):
- wherein:
- R1 and R3 independently are hydrocarbyl or substituted hydrocarbyl;
- R2 is R4(O)C—, wherein R4 is hydrocarbyl or substituted hydrocarbyl;
- Z is sulfur;
- k is an integer of 1 or greater;
- and
- n is an integer of 1 or greater.
A polymer blend composition comprising a polymer and a composition comprising compounds of Formula (I):
- wherein:
- R1 and R3 independently are hydrocarbyl or substituted hydrocarbyl;
- R2 is R4(O)C—, wherein R4 is hydrocarbyl or substituted hydrocarbyl;
- Z is sulfur;
- k is an integer of 1 or greater;
- and
- n is an integer of 1 or greater.
A process for modifying performance properties of polymers, the process comprising contacting a polymer with a composition comprising compounds of Formula (I) to form a polymer blend composition, wherein the polymer blend composition has an improved performance property relative to an unmodified polymer, the compounds of Formula (I):
- wherein:
- R1 and R3 independently are hydrocarbyl or substituted hydrocarbyl;
- R2 is R4(O)C—, wherein R4 is hydrocarbyl or substituted hydrocarbyl;
- Z is sulfur;
- k is an integer of 1 or greater;
- and
- n is an integer of 1 or greater.
