[PROBLEMS] To provide a novel comb-shaped diol and an inexpensive extrusion molding aid comprising the diol and a diisocyanate compound, having high shape retention and improved adhesion. A comb-shaped diol represented by the formula (1) (However, R 1 , R 2 , and R 3 are a hydrocarbon group which may be substituted with a halogen element, Y, Y ′ and Y ″ are hydrogen, a methyl group or a methylene chloride group, and Y and Y ′ are the same.) said may be. also, Z and Z 'are oxygen, to no sulfur is CH 2 group, Z and Z' good .R 4 be the same or different is Aruchiren group having 2 to 4 carbon atoms And k is an integer of 0 to 15.) and an extrusion molding aid comprising the comb-shaped diol, a water-soluble alkylene glycol and diisocyanate. |
