ABSTRACT:
Shaped articles are produced from a finely particulate material as aggregate and an aqueous binder preparation containing an acrylate polymer by moistening the aggregate with the binder preparation, making it into the desired shape and then drying it, using a binder preparation whose binder is an acrylate polymer whose glass transition range is relatively high and which is formed from (A) a predominant amount of methyl methacrylate, (B) a minor amount of (meth) acrylic acid, (C) a minor amount of an optional alkyl acrylate and (D) a small optional amount of another specific polymerizable compound.
