A semi-flexible shock-absorbing polyurethane foam is a reaction product of:
(a) a polyether triol having an hydroxyl number of from 25 to 115;
(b) a bulky modifying compound soluble in said triol (a) and having a single reactive hydrogen site, selected from:
(i) naphthalene substituted with -OH, -COOH, -NH2, or-SH;
(ii) anthrscene substituted with -OH, -COOH, -NH2, or-SH;
(iii) phenanthrene substituted with -OH, -COOH, -NH2, or -SH;
(iv) hydroabietyl alcohol; and
(v) dehydroabietyl amine;
(c) an aromatic polyisocyanate reactive with (a) to form a polyurethane;
(d) at least one blowing agent selected from water and low boiling volatile organic liquid polyurethane blowing agents;
(e) at least one substance which is a polyurethane chain-extender or crosslinking agent having at least two reactive hydrogens; and
(f) a catalyst for polyurethane-forming reaction between the said triol (a) and the said polyisocyanate (c).
A method of making the foam is described.
