    Abstract: The present invention relates to propylene copolymers grafted to alpha , beta -ethylenic unsaturated carboxylic acids or carboxylic acid derivatives, comprising ai) a random propylene copolymer (A1) containing from 0.1 to 15 % by weight of copolymerised C2- to C10-alk-1-enes, or a2) a propylene copolymer (A2), a random propylene copolymer (I) containing from 0.1 to 15% by weight of copolymerised C2- to C10-alk-1-enes and a random propylene copolymer (II) containing from 15 to 80% by weight of copolymerised C2- to C10-alk-1-enes, or a3) a propylene copolymer (A3) comprising a propylene homopolymer (III) and a random propylene copolymer (IV) containing from 15 to 80% by weight of copolymerised C2- to C10-alk-1-enes, obtainable by reacting the monomer to be grafted with the propylene copolymer (A1), (A2) or (A3) at pressures of from 1 to 300 bar, where, in the presence of from 0.005 to 0.5% by weight of an initiator which decomposes to give free radicals, from 0.01 to 1.0% by weight of the monomer to be grafted, where both concentrations are based on the propylene copolymer, is mixed with the molten propylene copolymer, and the grafting reaction is carried out at from 200 to 350@C.

    Abstract: The invention relates to a sheet-like composite material comprising a polyolefin matrix and natural fibre mats as reinforcing material, where the natural fibres have a fibre weight of greater than 10 tex. Preference is given to sisal fibres. The composite materials are used, in particular, in automobile production.

    Abstract: Shaped article (A) of melamine-formaldehyde foam that has formaldehyde emission below 0.1 ppm, as measured by DIN 556661. Shaped article (A) of melamine-formaldehyde foam that has formaldehyde emission below 0.1 ppm, as measured by DIN 556661, is prepared by: (a) generating a foam from a precondensate having melamine:formaldehyde mole ratio over 0.5; (b) conditioning the foam at below 200[deg]C; and (c) compressing the foam, in a press, at 160-240[deg]C and 5-100 bar (absolute) for 15-120 s. Independent claims are also included for the following: (1) method for preparing (A), as described; and (2) melamine-formaldehyde foam with formaldehyde emission below 0.1 ppm, prepared by steps (a) and (b) above.

    Abstract: Composite sheet material (I) is claimed, with a polypropylene (PP) matrix (II) and fibre mat reinforcement (III), i.e. a GMPP composite. At least 5 wt.% of the matrix (II) consists of recycled beverage bottle tops. Also claimed is a process for the prodn. of (I) which comprises melting the bottle tops (opt. after cleaning and crushing) in an extruder and opt. mixing with other matrix components (B,C,D; see below), and then pressing the melt together with fibre mat (III). Pref. matrix (II) contains (A) 5-100 wt.% recycled bottle tops, (B) 0-95 wt.% fresh PP, (C) 0-80 wt.% thermoplastic other than (B) and (D) recycled fibre-reinforced PP. Component (A) contains 80-100 wt.% heterophase polypropylene/polyethylene copolymer contg. 4-15 wt.% ethylene units and 20-0 wt.% EVA copolymer contg. 4-15 wt.% vinyl acetate units. (I) contains 20-60 wt.% glass fibres mat (III). USE/ADVANTAGE - Used for the prodn. of compression moulded or deep-drawn parts for cars, machine construction, domestic appliances etc.. The invention enables the prodn. of a useful GMPP material partly or wholly from recycled bottle tops, e.g. screw tops from soft drink bottles.
