EMULSION POLYMERS WHICH PROVIDE SCRUB RESISTANCE AND BLOCKING RESISTANCE IN HIGH AND LOW PVC PAINT FORMULATIONS |
摘要 |
An aqueous emulsion is made in a two-stage polymerization. In the first stage, monomers which give rise to a low Tg polymer are polymerized, whereas in the second stage, monomers which give rise to a high Tg polymer are polymerized. In one or both of the stages, a monomer having at least two carboxyl or carboxylate groups forms part of the monomer mixture. The resulting polymer is particularly useful in coating compositions, where it provides a good combination of blocking and scrub resistance.
