This invention relates toa thermosetting plastisol dispersion composition comprising(1) at least one copolymer of acrylonitrile-butadiene-styrene (ABS) in powder form, which is insoluble in the reactive plasticizer at room temperature and plasticizable at a temperature at or above the fluxing temperature;(2) a liquid reactive plasticizer member of the group consisting of (a) at least one epoxide resin having an average of more than one epoxide group in the molecule, (b) at least one liquid monomer, oligomer or prepolymer characterized by (1) containing at least one ethylenically unsaturated group and (2) capable of solvating the ABS at the fluxing temperature, and (c) a mixture of (a) and (b); and(3) an effective amount of either a thermal initiator or photoinitiator for plasticizers present in the composition.The plastisol dispersion after fluxing can form a thermoset sealant, coating or adhesive after the crosslinking reaction. |
