The invention relates to polymer mixtures which comprise a polyphenylene ether, a polyamide and an agent to improve the impact resistance. The agent is an olefinic based polymer such as an ethylene-propylene copolymer or an ethylene-propylene-non-conjugated diene terpolymer, on which a vinylmonomer having a carboxylic acid group or a derivative thereof or on which a vinylmonomer having an epoxy group has been grafted or an alkylene-alkyl(meth)acrylate copolymer having an alkylene group with 2-6 carbon atoms and having an alkyl group with 1-8 carbon atoms or an alkylene-alkyl(meth)acrylate having a functional group, which functional group has been introduced either by a polymerisation reaction while forming a terpolymer or by a grafting reaction, the functional group being selected from carboxylic acid groups, acid anhydride groups, acid amide groups, imido groups, carboxylic acid ester groups, amino groups, hydroxyl groups or epoxy groups and in which the alkylene group of the alkylenealkyl(meth)acrylate comprises 2-6 carbon atoms and the alkyl group thereof comprises 1-8 carbon atoms.

Polymer mixture which comprises a polyamide, a polyphenylene ether and

The present invention provides for a roof ridge ventilator cover that is adapted to be removably secured to a conventional roof ridge ventilator. The roof ridge ventilator cover of the present invention, when installed on a conventional roof ridge ventilator, will cover and block the air vents of the ventilator. The roof ridge ventilator cover generally includes two panels serving to cover and block the two panels of air louvers or vents of the roof ridge ventilator. The roof ridge ventilator cover may be made from sheet aluminum or other sheet material, including sheet made of plastic, having sufficient resilience to return unaided to a formed shape after some deflection. The roof ridge ventilator cover is installed by deflecting the cover sufficiently so the cover may be placed over the top portion of the roof ridge ventilator. The resilience of the roof ridge ventilator cover urges the cover back to an original shape to effectuate blocking the air vents of the roof ridge ventilator and further to connect the cover to the ventilator.
