ACRYLIC RUBBER MODIFIER AND NITRILE-BUTADIENE RUBBER COMPRISING THE SAME

摘要

PURPOSE: An acrylic rubber modifier is provided to improve heat resistance and mechanical property of a nitrile-butadiene rubber without the degradation of a curing rate due to excellent reactivity with the nitrile-butadiene rubber. CONSTITUTION: An acrylic rubber modifier is formed by copolymerizing (i) 45-97 parts by weight of an alkyl(meth)acrylic acid ester monomer with C2-14 alkyl group, (ii) 0.5-50 parts by weight of a hydrophilic monomer, and (iii) 0.5-5 parts by weight of a monomer containing a functional group crosslinkable with the nitrile-butadiene rubber.
