Title:
ブロックコポリマーならびにその製造方法および使用
Document Type and Number:
Japanese Patent JP5259901
Kind Code:
B2
Abstract:
The invention relates to block copolymers that are obtained by polymerizing a mixture of olefinically unsaturated monomers consisting of: a) 0 to 40 weight % of one or more ethylenically unsaturated ester compounds of formula (I), wherein R represents hydrogen or methyl, R<1> represents a linear or branched alkyl radical having 1 to 5 carbon atoms, R<2> and R<3> independently represent hydrogen or a group of formula COOR', wherein R1' represents hydrogen or an alkyl group having 1 to 5 carbon atoms; b) 10 to 98 weight % of one or more ethylenically unsaturated ester compounds of formula (II), wherein R represents hydrogen or methyl, R4 represents a linear or branched alkyl radical having 6 to 15 carbon atoms, R<5> and R<6> independently represent hydrogen or a group of formula -COOR'', wherein R'' represents hydrogen or an alkyl group having 6 to 15 carbon atoms, c) 0 to 80 weight % of one or more ethylenically unsaturated ester compounds of formula (III), wherein R represents hydrogen or methyl, R<7> represents a linear or branched alkyl radical having 16 to 30 carbon atoms, R<8> and R<9> independently represent hydrogen or a group of formula -COOR''', wherein R''' represents hydrogen or an alkyl group having 16 to 30 carbon atoms, d) 0 to 50 weight % of comonomers, whereby the mixture of ethylenically unsaturated monomers is discontinuously modified during chain growth with the purpose of obtaining block copolymers whose blocks have at least 30 monomer units. The novel copolymers are used as setting point improvers.
