Abstract: Parent patent DT 2345484 describes a bituminised roofing strip contg. a non-woven random-spun web of synthetic polyester filaments as support. According to present Patent of Addn., random web consists of synthetic polyester filaments having m.pt >=250 degrees C, esp. of polyethylene terephthalate filaments having individual titre 3-15 dtex, which are impregnated and bonded with 10-30 wt. %, w.r.t. non-soaked web, of an aq. neutral to weakly alkaline binder dispersion with 10-60 wt. % solids contg. a copolymer contg. by wt. 45-55% acrylate or methacrylate of 1-8C monohydric alcohols, 24-30% acrylonitrile, 12.5-30 % styrene, 0.5-2.5 % acrylamide, prepd. by emulsion polymerisation in presence of anion-active and/or non-ionic emulsifiers and activators, and 10-30 wt. % melamine-HCHO pre-condensate, so that stretch sail-like reinforcements are present between filaments. Reinforced fleece has surface wt. 80-300 g/m2, strength 20-100 kp/5 cm; elongation at break 25-50%; further tear strength 4-9 kp. Bituminised strip has tear-strength 30-100 kp/5 cm, elongation at break 20-60% elastic extension 1-5%, further tear strength 2-8 kp. nail tear out resistance 13-30 kp and bending strength >5000 revolutions.
