<p>Polyvinyl chloride pastes and plastisols having good foam forming properties and low viscosity are made from resins produced by (co)polymerising vinyl chloride in the presence of an alkyl sulphate or alkyl sulphate mixture having at least 30 %, preferably at least 50 %, branching. Alternatively the branched alkyl sulphate or mixture can be compounded with the polymer after polymerisation.</p> |
