Plasticised polyvinyl alcohol (PVA) suitable for thermoplastic processing contains >=70wt.% particles of 0.8-4 mm dia. in which the plasticiser is homogeneously dispersed. It is made by mixing 100 pts. dry PVA granulate with 5-50 parts plasticiser in presence of insufficient water to completely dissolve the PVA, the heating and subsequent cooling to swell and temporarily agglomerate the particles. A free-flowing non-tacky granulate is obtd. from dry polymer with improved mechanical properties in the product due to homogeneous dispersion of the plasticiser. Removal of the water is unnecessary.
