The invention relates to chlorine-free polyolefin-based plastisols or organosols and to methods for producing the same. According to the invention, the plastisol or organosol consists of the following: (a) a finely-dispersed polyolefin in (b) a dispersion agent in quantities of 60 to 800 parts by weight, in relation to 100 parts by weight polyolefin a), made up of monomers which are capable of polyaddition or which are polymerisable and copolymerisable, and/or oligomers and/or prepolymers and optionally, liquid softeners; and (c) an initiator system which is suitable for the desired polyaddition and/or polymerisation and copolymerisation in quantities known per se; (d) optionally, up to 700 parts by weight inert fillers and other usual additives and auxiliary substances, in relation to 100 parts by weight polyolefin a); and is produced in certain conditions. The result is a chlorine-free plastisol or organosol which is storage-resistant at room temperature and which gelates at high temperatures. The inventive plastisols or organosols are suitable for many applications and represent an advantageous alternative to the plastisols currently in use, e.g. PVC-based plastisols, since they guarantee a number of different combinations of properties. |
