The materials comprise transparent copolyamides that contain: (A) 40 to 100 wt % of at least one transparent copolyamide with a glass transition temperature (Tg) of at least 80° C. and not more than 150° C., composed of at least two diamines that are different from each other, wherein the at least two diamines are a mixture of (a) 50 to 90 mol % bis-(4-amino-3-methylcyclohexyl)methane (MACM) and/or bis-(4-amino-3-ethylcyclohexyl)methane (EACM) and/or bis-(4-amino-3,5-dimethylcyclohexyl)methane (TMACM) and b) 10 to 50 mol % aliphatic diamine having 9 to 14 carbon atoms, in particular decandiamine, particularly preferably at least 20 mol % decandiamine, each relative to the total amount of diamines, and of one or more aliphatic dicarboxylic acids, having 6 to 36 carbon atoms, (B) 0 to 60 wt % of at least one further polymer, (C) 0 to 10 wt % of additives, the sum of the components (A), (B) and (C) totaling 100% by weight.



Composition for forming intermediate film for laminated glass, intermediate film for laminated glass and laminated glass

Tue, 19 May 2015 08:00:00 EDT

The object of the present invention is to provide an intermediate film for laminated glass which prevents reductions of transparency and appearance property caused by permeation of moisture and water. The above object is attained by the present invention, i.e., a composition for forming an intermediate film for a laminated glass which comprises ethylene-vinyl acetate copolymer and a compound having alkyleneoxy group. The composition of the present invention enables the formation of an intermediate film for a laminated glass that restrains white spots from occurring by the permeation of moisture and water.

Curable fiberglass binder comprising salt of inorganic acid

Tue, 19 May 2015 08:00:00 EDT

Formaldehyde-free binder compositions are described that include an aldehyde or ketone, a nitrogen-containing salt of an inorganic acid, and an acidic compound. The acidic compound may be an organic acid, such as maleic acid or citric acid among others. The acidic compound is supplied in quantities that lower the pH of the binder composition to about 5 or less. The binder compositions may be used in methods of binding fiberglass and the resulting fiberglass products have an improved tensile strength due to the addition of the acidic compound.
