摘要:
An oxide fine particle-containing resin composition is produced by mixing: (A) silicon oxide fine particles and/or metal oxide fine particles; and (B) an organic polymer having a silyl group in which a hydrolyzable group and/or a hydroxyl group is bonded to the silicon atom, in an organic solvent in the presence of a basic compound, an acidic compound or a metal chelate compound, thereby dispersing the oxide fine particles (A) in the organic solvent. The oxide fine particle-containing resin composition is a silyl group-containing resin composition in which the oxide fine particles are highly dispersed and gives a silyl group-containing resin cured product excellent in transparency and resistant to yellowing discoloration.

Water-continuous emulsion of silylated elastomeric polymers are disclosed having a solids content of greater than 75%, an average particle size ess than 5µ, and having sufficient stability to produce a stable lower solids emulsion upon dilution with water comprising; a silylated elastomeric polymer, surfactant, water, optional plasticizer, and optional low molecular weight acid.The water-continuous emulsions of silylated elastomeric polymers can be prepared by; (I)forming a premix comprising an elastomeric polymer and surfactant, and optionally a plasticizer and low molecular weight acid, and (II) adding water to the premix with mixing to form a water continuous emulsion of the silylated elastomeric polymer having a solids content of greater than 75%, an average particle size less than 5µ, and having sufficient stability to produce a stable lower solids emulsion upon dilution with water.
摘要:
A crosslinkable polymer composition comprises an olefin copolymer or graft copolymer with hydrolysable silane groups and a silanol condensation catalyst, as well as a silane compound with at least one hydrolysable organic group. The polymer composition is characterised in that the silane compound has a compatibility with the polymer composition of at least 0.035 mole hydrolysable groups per 100 g polymer composition, and in that the silane compound is represented by the general formula: R1(SiR2nX3-n)m, wherein R1 is a monofunctional hydrocarbyl group having 13-30 carbon atoms, or a difunctional hydrocarbyl group having 4-24 carbon atoms, R2 is a hydrocarbyl group having 1-10 carbon atoms, X is a hydrolysable organic group, n is 0, 1 or 2, and m is 1 or 2.
摘要:
A process for producing a solid dispersion comprising a resin and a functional compound dispersed therein, which comprises: kneading a powdery functional compound together with deionized water while gradually introducing the deionized water; adding a resin and, according to need, an additive to the mixture; subsequently heating and kneading the resultant mixture in a vessel which has an atmosphere causing the resin to soften at a temperature not higher than the boiling point of the deionized water and which has been tightly closed according to need so as to function like a pressure cooker to thereby disperse the functional compound into the softened resin; and kneading the resultant dispersion with heating at ordinary pressure or a reduced pressure to remove the water by vaporization.

摘要:
Water-continuous emulsion of curable elastomeric polymers are disclosed having a solids content of greater than 75%, an average particle size less than 5 µm, and having sufficient stability to produce a stable lower solids emulsion upon dilution with water comprising; a curable elastomeric polymer, surfactant, internal cure additive, water, optional plasticizer, and optional low molecular weight acid. The water-continuous emulsions of curable elastomeric polymers can be prepared by mixing an elastomeric polymer, surfactant, internal cure additive, and optionally a plasticizer and low molecular weight acid, with water to form a water continuous emulsion of the curable elastomeric polymer having a solids content of greater than 75%, an average particle size less than 5 µm, and having sufficient stability to produce a stable lower solids emulsion upon dilution with water.
