Abstract
50 years old paper sheets have been treated with different concentrations o f PVAc/PV versatate copolymer dispersion. The effect of different dipping r ime, of washing before treatment, of adding DOP to the copolymer dispersion and of heat pressing after treatment were studied. The probes were aged at 80 degrees C and different humidities of 30 to 94%. Ageing at 80 degrees C and 94%, was also done for several time intervals. As a result it can be s aid that the polymer treatment is highly improving the mechanical propertie s of the paper and its; ageing stability.
