1. A cellulosic-reinforced composite comprising:
- (a) 35 to 85 wt. % polyolefin matrix polymer consisting of;
(i) a high density polyethylene resin having a density in the range 0.935 to 0.970 g/cm3 and(ii) a silane copolymer, the weight ratio of said high density polyethylene to said silane copolymer ranging from 50;
1 to 1;
50; and
(b) 15 to 65 wt. % cellulosic filler.
