Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
113 words
In a process for producing a dimensionally stable polyolefin molding, the improvement comprising the use of a member selected from the group consisting of (A) at least one compound (I) as the dimensional stabilizer and (B) a mixture of the at least one compound (I) with at least one ordinary pigment as the colorant, the at least one compound (I) being represented by the following general formula: ##STR13## wherein ##STR14## is the residue of an organic diamine containing 1 to 3 aromatic rings, X is a halogen atom and n is an integer from 1 to 4, said compound (I) being used in an amount of 0.0001% to 1% by weight of polyolefin.
