Abstract
A method modifies the rheology of a polymeric material through incorporation in the polymeric material a modifier blend having a) a radical initiator selected from peroxides, carbon-based radical generators, bis-azo compounds, or stable nitroxyl compounds, and b) thiourethane of the formula (1). A modified polymeric material is obtainable by incorporating in the polymeric material the modifier blend.
Claims18
A method for modifying the rheology of a polymeric material, the method comprising:
- incorporating in the polymeric material a modifier blend comprising
- a) a radical initiator selected from a group consisting of a peroxide, a carbon-based radical generator, a bis-azo compound, and a stable nitroxyl compound, and
- b) a thiourethane of formula (1)
- where
- Ra is based on an organic isocyanate,
- at least one radical —S—Ra is introduced by reaction with an isocyanate group,
- Rb is a C2-C40 alkyl which is optionally substituted and/or interrupted, and
- n is equal to or greater than 1.
