Process for the production of cement-synthetic polymer composite molded bodies

摘要

A composite, molded article is prepared by forming a W/O emulsion containing a vinyl monomer, water, a cement, a polymerization initiator and an emulsifier, followed by molding and hardening. The emulsifier includes a neutralization product of an amide-containing amine with an organic sulfonic acid or an organic acid phosphate. The amide-containing amine is a condensation product obtained by reacting a fatty acid having 8-24 carbon atoms with an amino compound having the general formula (I) or (II): R1R2N[(CH2)x-NH]yH(I) R3N[(CH2)zNH2]2 (II) wherein R1, R2, R3 each represent, independently from each other, hydrogen, an alkyl group haaving 1-24 carbon atoms or an alkenyl group having 1-24 carbon atoms, x is an integer of 1-4, y is an integer of 1-8 and z is an integer of 1-4.
