Document Type and Number:
Japanese Patent JP5594708
Kind Code:
B2
Abstract:
The present invention provides a preparation method of hyperbranched polycarboxylic acid type copolymer cement dispersant, including: Monomer A, B and C undergo a free radical copolymerization in an aqueous medium. The molar ratio of Monomer A, Monomer B and Monomer C conforms to B/A-A-2-10 and C/(A+B-C)-0.02-0.08. Monomer A is expressed by General Formula (1), where R 1 is H or a methyl; X 1 =O, CH 2 O, CH 2 CH 2 O; m is an integer from 5 to 200. Monomer B is expressed by General Formula (2), where R 2 is H or COOM; R 3 is H or CH 3 and M is H, Na, K or NH 4 ; Monomer C is expressed by General Formula (3), where R 4 is H or methyl; X 2 =O, CH 2 O, CH 2 CH 2 O; Y=CH 2 , CH 2 CH 2 , CH(CH 3 ), CH 2 CH 2 CH 2 , CH(CH 3 )CH 2 , C(CH 3 ) 2 and n is an integer from 5 to 200.
