A polyamide-based polymer composition including: a) 50% to 98% by weight of a transparent amorphous polyamide; b) 1% to 15% by weight of a polymer in the form of core-shell particles; and c) 1% to 15% by weight of a polyether block and polyamide block copolymer, wherein the polyether block and polyamide block copolymer has: as a 2 mm layer, a transmittance at 560 nm of 90% or more; and a refractive index that does not differ by more than 0.01 from that of the transparent amorphous polyamide and wherein the polymer in the form of core-shell particles has a refractive index that does not differ by more than 0.01 from that of the transparent amorphous polyamide. Also, a process for the manufacture of the composition, and the composition capable of being obtained by said process.

Transparent polymeric composition

A transparent antistatic composition based on polymethyl methacrylate (PMMA), including: 55% to 99.9% by weight of PMMA, and 0.1% to 45% by weight of at least one polyamide (PA) block-containing and polyether (PE) block-containing copolymer (PEBA) comprising polyethylene glycol (PEG), with respect to the total composition weight, the copolymer includes in the range 50% to 80% by weight of PEG with respect to the total weight of copolymer.

Transparent and antistatic PMMA composition

The present invention relates to the use of thermoplastic starch in the manufacture of an adhesive and ultrathin waterproof-breathable film, said thermoplastic starch being provided in the form of an alloy with hydrophilic TPE comprising at least 10% by weight, preferably at least 20% by weight, preferably at least 30% by weight, preferably at least 40% by weight, preferably at least 50% by weight, of polyethylene glycol (PEG), with regard to the weight of the TPE. This film can be used in a textile product in the medical field, hygiene, luggage, the clothing industry, the garment industry, domestic or household equipment, furniture, fitted carpets, the automobile industry, industry, in particular industrial filtration, agriculture and/or the construction industry.
