a porous polyacrylate latex film was formed at ambient temperature from polyacrylate core-shell emulsion incorporated with diacetone acrylamide (DAAM).The effects of shell composition of core-shell emulsion
ADH content
porogen content and porogen type on the permeability of latex film were investigated.The results showed that the latex particles with BA/(MMA+AA+DAAM)=2.5/2.5(mass ratio) in shell composition could not fuse completely into a continuous dense film
but formed granular deposits.Then
a loose and porous latex film with high permeability was formed with the help of porogen.The investigation further revealed that the restricted movement of polymer chains contributed to the maintenance of porous structure in the latex film and then high permeability.In addition
the study indicated that the latex films with high permeability were formed with glucose or polyethylene glycol (PEG300)as porogen.
