摘要
<p>Prodn. of moulded articles from a mixt. of (a) crosslinked urethane and/or urea gp. contg. isocyanate polyaddition prod. with a density of 0.005-1.8 g/cm3 and opt. contg. a filler and/or a reinforcing agent; (b) 0.01-10,000 pts.wt. per 100 pts. of (a) of an opt. filler and/or reinforcing agent contg. thermoplastic polymer; and (c) 1-20 pts.wt. of a recycling additive selected from (c1) an amorphous polyolefin with a MW of 10000-150000 and an inhomogeneity of 1-6.5; (c2) a chemically modified amorphous polyolefin of MW 10000-100000 and an inhomogeneity of 1-6.5 and contg. 2.5-50 wt.% of C1 and 0.5-17.5 wt.% of gps. contg. N,O,S and/or Si; and (d) other additives. ADVANTAGE - Improved compatibility and mechanical properties.</p>
