Abstract: The invention relates to a device for thermal treatment of air for a vehicle, including a conveying duct, a heating duct and a mixing chamber. A mixing device is configured to be able to move between a first end position, which prevents air from circulating between the conveying duct and the mixing chamber, and a second end position, which prevents the air from circulating in the heating duct. The mixing device includes a main flap and a deflection element projecting from the main flap, the deflection element including at least one front rib and at least one lateral rib extending one end of the front rib.

Abstract: This composition, which is useful as a binder in the preparation of synthetic resin concretes or mortars, bonding primers or finishing coats, comprises (A) a system of monomers comprising: (a1) 50-90 parts of a dicyclopentenyloxyalkyl eater: where R=H or CH3; n=1 or 2; and R1=C2-C6 alkylene; (a2) 0-25 parts of at least one heavy (meth)acrylate giving a homopolymer with a Tg higher than that of a homopolymer of (a1); (a3) 0-25 parts of at least one heavy (meth)acrylate giving a homopolymer with a Tg lower than that of a homopolymer of (a1); (a4) 0-25 parts of at least one monomer containing at least two (meth)acrylic unsaturations; and (B) 5-30 parts of at least one poly(allyl glycidyl ether); and (C) an initiating system chosen from (C1) to (C4): (C1) 0.1-3 parts of at least one organic peroxide derived from a C3-C18 hydrocarbon compound and 0.1-2 parts of at least one aromatic amine; (C2) 0.

Abstract: The application discloses a functionalized multiblock macromonomer of formula: ##STR1## or of formula: ##STR2## in which formulae: each of the blocks A, B and C represents a sequence of a monomer chosen from the acrylic, vinylaromatic, methacrylic, diene, vinylpyridine, vinylpyrrolidone, alkylene oxide, lactam, lactone and maleimide monomer classes, on condition that at least one of the blocks A and C is chosen from a different class to that of block B and that at least one of the blocks A, B or C is a (meth)acrylic sequence,m, n and p are integers representing the number of monomer units in the sequence under consideration, such that 3.ltoreq.n.ltoreq.1000, 0.ltoreq.m.ltoreq.1000 and 0.ltoreq.p.ltoreq.1000, on condition that m and p are not 0 at the same time, andF is a group terminated by O.sup.-, by OH, by an .alpha.,.beta.-ethylenic unsaturation, or by an oxirane groups.
