초록 ▼

Increasing the solids content of an aqueous dispersoid of: (a) a resin having aliphatic backbone carbons; (b) addition polymer, and (c) graft polymer consisting of addition polymer grafted to the aliphatic carbon atoms of said resin; which comprises bringing together ethylenically unsaturated monomer, initiator, and such dispersoid, and polymerizing the such monomer in situ. Preferred products produced are water-reducible epoxy resin-based. These are produced by a process which comprises initiating addition polymerization of ethylenically unsaturated monomer in the presence of such dispersoid.

대표청구항 ▼

A process for addition polymerizing through its ethylenic unsaturation a quantity of Q parts by weight of addition polymerizable ethylenically unsaturated monomer in an aqueous medium using free radical initiation which comprises: (a) incorporating a quantity Q of an ethylenically unsaturated addition polymerizable monomer and initiator therefor, in an aqueous, liquid reaction medium that is a dispersion in an aqueous vehicle of a resinous dispersoid of at least 0.3 Q to about 20 Q or more of at least one ionized polymer comprising a graft copolymer having a backbone including aliphatic carbon atoms on which an ionizable addition polymer side chain is bonded by a carbon-to-carbon bond in place of a hydrogen atom that is bonded thereto in the ungrafted state, said graft copolymer being formed by grafting at least one addition polymerizable monomer, including ionizable monomer, onto a polymer substrate selected from the group consisting of: homopolymers and copolymers of vinyl chloride; homopolymers and copolymers of acrylic monomers; hydrocarbon resins from butadiene, styrenes, and coumaroneindenes; polyurethanes; polyesters; and aromatic epoxy resins; to form at least one side chain bonded by carbon-to-carbon grafting to one of said backbone carbons, the ionization being on the side chain, and from zero up to about 20 Q of at least one other polymer that is selected from said group and that is not appreciably ionic in nature, thereby providing an initial reaction medium having a continuous aqueous liquid phase and polymeric dispersed phase, said reaction medium also including an amount up to 200% by weight of said resinous dispersoid of an organic liquid that is miscible with water and that comprises a solvent for at least some of the solids of said dispersoid; (b) polymerizing said monomer at a temperature at least as high as about room temperature and under pressure sufficient for keeping the continuous aqueous phase in a liquid state, and in the presence of a sufficient amount of said initiator for causing addition polymerization of said monomer at said temperature; the amount of water initially present in said aqueous vehicle and any amount of water that is added during said addition polymerization being sufficient for keeping the solids content of the reaction mixture from step (b) above from exceeding about 60% by weight of the reaction mixture at any time.
