Polycarbodiimide copolymer and production method thereof |
| abstract |
A polycarbodiimide copolymer which comprises at least one structural unit selected from rubber residues represented by the following formulae (1) and (2) in a number “m”: n nand a structural unit represented by the following formula (3) in a number “n”: n nand which comprises on both termini a terminal structural unit derived from a monoisocyanate, wherein m is an integer of 2 or more, n is an integer of 1 or more, m+n is from 3 to 1,500 and m/(m+n) is from 1/1,500 to ⅓. The polycarbodiimide is capable of keeping the inherent heat resistance and also showing excellent flexibility. Films and molding materials having high heat resistance and flexibility can be obtained. |
