摘要： A resin composition for cement which comprises a polymer obtained by emulsion polymerization of a dicyclopentadiene derivative represented by formula (I). An unsaturated epoxy ester, an alpha , beta -unsaturated carboxylic acid and an ethylenically unsaturated monomer copolymerizable with these three components is disclosed. The use of the composition by mixing with cement is also disclosed.
