Aqueous dispersions of olefinic resin compositions and process for preparation thereof |
摘要 |
An aqueous dispersion of an olefinic resin composition having improved properties which comprises mixing an olefinic resin composition comprising (a) 50 to 99% by weight of a carboxyl-free olefinic resin having an intrinsic viscosity of 0.1 to 5 and (b) 1 to 50% by weight of a carboxyl-containing modified olefinic resin having an intrinsic viscosity of 0.04 to 1 and an acid number of 30 to 150, the amount of each resin being based on the total amount of resins (a) and (b), which has been melted by heating to a temperature above the melting point, whichever is higher, of the resins, with an aqueous medium heated to a temperature of 140 to 300 DEG C. in the presence of at least 0.2 chemical equivalent, to the carboxyl groups of resin (b), of a base.
