Polymer compositions |
| 摘要 |
<p>The open time of a cementitious composition, such as a grout, may be increased by the incorporating therein, as a binder, a polymer composition comprising a film-forming copolymer formed by polymerisation of a monomer mixture comprising 1 to 3% of at least one monomer selected from the group of monomers consisting of amides of alpha , beta -unsaturated C3 to C6 carboxylic acids and N-vinyl lactams, and at least one hydroxy-(C1 to C8)alkyl (meth)acrylate monomer, wherein the total amount of these monomers is from 2 to 7.5% by weight of said monomer mixture.</p> |
