<p>This improved fibre-reinforced heat-resistant polyolefin composition comprises 5-85 wt.% of polyphenylene sulphide (A), 15-95 wt.% of modified polyolefin (B) and 10-60 pts. wt. of reinforcing fibres (C) to 100 pts. wt. of the sum of (A) and (B). The modified polyolefin (B) has a melting point of 200 deg. C or higher and is partly or wholly graft-modified within a range of 0.01 to 10 wt.% with an unsatd. carboxylic acid or a deriv. thereof. The basic polyolefin of (B) is specified to be poly4-methyl-1-pentene or poly3-methyl-1-butene. Oxazoline-modified polystyrene (D) is added, if necessary, to the above-mentioned compsn. to the amt. of 5-30 pts. wt. per 100 pts. wt. of the sum of (A) and (B). If necessary, additives such as heat-stabiliser, weather-stabiliser, dyes, antiraster etc. can also be added in amts. that do not interfere with the purpose of this invention.</p> |
