Abstract:
Disclosed are a polysiloxane-modified polyhydroxy polyurethane resin characterized by being derived from a reaction between a 5-membered cyclic carbonate polysiloxane compound represented by the below-described formula (1) and an amine compound, and its production process; and a resin composition, thermal recording medium, imitation leather, thermoplastic polyolefin resin skin material, weather strip material, and weather strip, all of which make use of the resin.
Abstract:
A film-forming, aqueous dispersion comprising at least one substantially random interpolymer comprising (A) polymer units derived from: (1) at least one vinylidene aromatic monomer, or (2) at least one hindered aliphatic or cycloaliphatic vinylidene monomer, or (3) a combination of at least one aromatic vinylidene monomer and at least one hindered aliphatic or cycloaliphatic vinylidene monomer, and (4) at least one C2-20 α-olefin; and (B) a surfactant. The aqueous dispersions or emulsions of the present invention are useful as barrier paper coatings, corrosion resistance coatings, carpet backing and carpet fiber binders, in some instances, precursors for high molecular weight polymers, composites and membranes for separation systems, coatings and binders for paints, inks, moisture barriers in packaging, fabric coatings, synthetic gloves, adhesives, foams, composite flooring tiles and layers, sound deadening composite foams and pads, automotive protective exterior coatings, and removable temporary protective coatings.
Abstract:
An artificial leather having a suede appearance and colours within the grey-black range and high colour fastness comprising a microfibrous component and an elastomeric matrix; the microfibrous component consisting of polyester microfibres having a count of 0.01 to 0.50 dtex; the elastomeric matrix consisting of polyurethane consisting of soft and hard segments; the ratio between the elastomeric matrix and the microfibrous component ranging from 20/80 and 50/50 by mass; the microfibrous component containing carbon black pigment in a percentage of 0.05 to 2.00% by mass; the elastomeric matrix containing carbon black pigment in a percentage of 0 to 10% by weight; the carbon black always having an average dimension smaller than 0.4 microns. The average length of the tassel is between 200 and 500 microns. The soft segments consist of at least one polycarbonate diol selected from polyalkylene carbonate diols and at least one polyester diol. The hard segments consist of urethane groups deriving from the reaction between free isocyanate groups and water. The total content of carbon black is between 0.025 and 6% by weight.
