摘要： The present invention provides efficient methods to form a high solids content polymeric polyacid or a comb polymer useful as a superplasticizer or dispersant which comprise heating to from 80 to 100C for a first time period, and then, sequentially, heating to a second temperature of from 150 to 250 °C for a second time period a wet reaction mixture having a solids content of from 80 to 99 wt.% and comprising from 15 to 60 wt.% of one or more ethylenically unsaturated acid or a salt thereof, from 37 to 76.99 wt.% of one or more polyether polyols, alkyl polyether polyols, polyether amines or alkyl polyether amines in the presence of (i) from 0.01 to 1 wt.%, of one or more water soluble radical initiators or redox pairs and (ii) from 2 to 22 wt.% of one or more phosphorus oxide containing compounds, all weights based on the total weight of the wet reaction mixture.

摘要： The present invention provides aqueous compositions comprising ß-hydroxy propyl gamma-polyoxyalkylene ether functional resins chosen from (poly)oxyalkylene ether ß-hydroxy propyl (meth)acrylates, maleates and itaconates, water soluble copolymers thereof, and mixtures thereof. The water soluble copolymers are comb polymers and (meth)acrylate, maleate and itaconate monomer resins can be addition polymerized to form comb polymers suitable for many uses, such as superplasticizers, dispersants, detergents and floor care compositions. In addition, the present invention provides methods of making the resins by reacting in water or aqueous solvent one or more reactant a) a glycidyl polyether or glycidyl ether, optionally having an alkyl or aryl end group with one or more reactant b) a carboxylate anion containing vinyl compound or polymer, preferably a polymer such as poly(meth)acrylic acid. The methods enable simple formation of comb polymers.
