Document Type and Number:
WIPO Patent Application WO/2019/124744
Kind Code:
A1
Abstract:
The present invention relates to a conjugated diene-based copolymer composition and, more specifically, provides a conjugated diene-based copolymer composition comprising: a first conjugated diene-based copolymer, which comprises 20-60 wt% of a repeating unit derived from an aromatic vinyl monomer, 35-75 wt% of a repeating unit derived from a first conjugated diene-based monomer and 1-10 wt% of a repeating unit derived from a hydroxyalkyl (meth)acrylate monomer, and has a Mooney viscosity (MV) of 30-120 at 100°C; and a second conjugated diene-based copolymer, which comprises 20-60 wt% of a repeating unit derived from α-methylstyrene monomer and 40-80 wt% of a repeating unit derived from a second conjugated diene-based monomer, and has an MV greater than 120 and less than or equal to 200 at 100°C.
