The polyvinyl acetal composition contains compound (C) at 0.05-0.75 times the mass of the total mass of polyvinyl acetal (A) and polyvinyl acetal (B).
The composition exhibits a first peak and a second peak derived from the polyvinyl acetal, when the polyvinyl acetal is analyzed by HPLC using an ODS column having an inner radius of 4 mm and a length of 1 cm.
The first layer (2) contains a polyvinyl acetal resin, a plasticizer and a tackifier.
Disclosed is an intermediate film for laminated glasses which contains a polyvinyl acetal resin.
The degree of acetylation of the polyvinyl acetal resin contained in the first layer (2) exceeds 30 mol%.
The purpose of the present invention is to provide a polyvinyl acetal film that has outstanding transparency and can suppress the phenomenon of heat cracking.
The compositions include an aqueous alkaline solvent soluble polymeric binder that includes a phenolic resin (such as a novolak) or a poly(vinyl acetal).
The purpose of the present invention is to provide a vinyl acetal-type polymer of which the viscosity can be reduced while keeping mechanical properties such as strength.
This carbon nanotube dispersion contains an alcoholic solvent (preferably a lower alcohol having from about 1 to about 4 carbon atoms) and a polyvinyl acetal resin.
Disclosed is a laminate of a layer that contains a polyvinyl acetal and a layer that contains a polyolefin, which exhibits excellent adhesion between the layers.
This film comprises: (1) a poly(vinyl acetal) in an amount of at least 50-70 weight %, (2) a second polymer, and (3) colloidal silica.
Specifically disclosed is an intermediate film for laminated glasses which contains 100 parts by weight of a polyvinyl acetal resin and 40-75 parts by weight of a plasticizer.
Disclosed is a polyvinyl acetal resin composition comprising a polyvinyl acetal resin (A) and a polyvinyl acetal resin (B) which is immiscible in the polyvinyl acetal resin (A).
