ABSTRACT:
A steering wheel is disclosed, which is produced by injection molding a resin composition comprising (i) a crosslinked vinyl chloride polymer having a gel fraction of at least 20% and a non-gelled portion having an average polymerization degree of from 2000 to 3000, (ii) a non-crosslinked vinyl chloride homopolymer having an average polymerization degree of from 800 to 1000, and (iii) a liquid plasticizer, wherein the weight ratio of polymer component (i) to polymer component (ii) is from 50/50 to 80/20 and (iii) the amount of liquid plasticizer is from 70 to 130 parts by weight per 100 parts by weight of the total amount of the two polymers (i) and (ii). The steering wheel has excellent properties with respect to uniformity in matte surface, wear resistance and lightfastness.
