Title:
RAPID LOW-TEMPERATURE PREPARATION METHOD FOR MIXING AMOUNT LOW SENSITIVE POLYCARBOXYLIC ACID
Document Type and Number:
WIPO Patent Application WO/2019/100372
Kind Code:
A1
Abstract:
Provided is a rapid low temperature preparation method for mixing amount low sensitive polycarboxylic acid, and the invention relates to a water soluble polycarboxylic acid containing polyether side chains. The mixing amount low-sensitive polycarboxylic acid is a polymer. The method comprises: irradiating an unsaturated ester macromonomer and an unsaturated monomer derivative to initiate free radical polymerization by a photoinitiator, to obtain a precursor; polymerizing the precursor and the unsaturated ether macromonomer, the unsaturated monomer derivative and the like by aqueous solution polymerization, so as to obtain the product. The polycarboxylic acid of the present invention has excellent low sensitivity properties, which is evaluated by a paste mixing amount sensitivity (Rp) and a concrete mixing amount sensitivity (Rc) of an additive.
