INVENDIGT MJUKAD POLYMERLATEX

摘要

Successive suspension polymerisations in at least two stages are used to prepare aqueous suspensions or latices containing particles whose middle part is made of hydrophilic and relatively soft polymer while the outer part is made of hydrophobic and relatively hard polymer, the two types of polymer interpenetrating to a sufficient degree to result in an internal plasticisation of the latex particles. These latices can be employed for preparing compositions of the polish type which make it possible to form hard, glossy coatings with a very high chemical and mechanical resistance on floors or parquets.
