Document Type and Number:
WIPO Patent Application WO/2008/032799
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a polycarboxylic acid polymer having high dispersing ability in various solid-powder systems. [MEANS FOR SOLVING PROBLEMS] The polycarboxylic acid polymer is one formed from a reactive alcohol derivative having a polymerizable bonding site and a dibasic acid derivative, and is characterized in that the reactive alcohol derivative has a polyalkylene oxide chain having an end part formed by C3 or C4 polyalkylene oxide addition, the content of the C3 or C4 alkylene oxide in the end parts being 0.1-30 mol% based on all alkylene oxide chains.
