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 a curable composition of norbornyl modified unsaturated polyester or polyesteramide resins blended with a polymerizable monomer such as styrene, an aggregate mixture such as sand and gravel and an effective amount of styrene acrylonitrile copolymers, styrene alphamethylstyrene copolymers, or a styrene acrylonitrile copolymer mixture with no more than 25% by weight polystyrene.
