Polymer concrete having high bond strength and long working time

摘要: Polymer concretes having a high bond strength and/or long working times are made from curable composition of norbornyl modified unsaturated polyester or polyesteramide resins blended with polymerizable monomer such as styrene, an aggregate mixture sand and gravel effective amount styrene acrylonitrile copolymers, alphamethylstyrene copolymer no more than 25% by weight polystyrene.
