Abstract:
PROBLEM TO BE SOLVED: To provide novel polymers containing carboxyl groups and polyalkylene ether side-chains. SOLUTION: The water-soluble or water-dispersible polymers containing carboxyl groups and the side-chains represented by formula (I) is obtained by radically copolymerizing the polymer having carboxyl groups on the monomers to be polymerized, 3 to 50 wt.% of an ethylenic unsaturated monomers A selected from the group consisting of ethylenic unsaturated 3-6C mono-carboxylic acids and their salts, 50 to 97 wt.% of an ethylenic unsaturated monomers B bearing the side-chains of formula I in the presence of 0.1 to 50 wt.% of a phosphorus-containing compounds such as phosphinic acid or phosphonic acid. The resultant polymer has a weight average molecular (Mw) of 5000 to 150000 dalton. The polymer has favorite property as an additive for mineral building materials. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
The present invention relates to the use of water soluble or water dispersible polymers containing carboxyl groups, optionally in latent form, and side-chains of general formula (I): -X-Y-[-O-(-Alk-O)n-R]k as additives in mineral building materials, wherein X, Y, Alk, R, n and k have the meanings cited in Claim 1. Said polymers can be obtained by polymerizing ethylenically unsaturated monomers in the presence of compounds containing phosphorus and, optionally, by additional polymer-analogous transformation. The invention further relates to the production of said polymers and the use thereof. Also described are polymers, which can be obtained by polymerizing aromatic vinyl compounds, olefins, cycloolefins and/or dienes, as D monomers and anhydrides of ethylenically unsaturated dicarboxylic acids as E monomers, and which can be used both as parent compounds for the above-mentioned polymers and as additives for mineral building materials.00000
Abstract:
A process for the preparation of a compound having the structure of Formula (I) wherein A, R1, R2, R3, Y and Z are as defined in the disclosure. The process includes reacting a heterocyclic amine with a monoaldehyde or a dialdehyde in a pH range of from about 8 to 14 and then quaternizing the so-reacted heterocyclic amine with an alkylating agent at a pH of not less than about 2. The use of a pH control substantially prevents formation of an undesirable protonated intermediate.
