Mechanical behaviour of block copolymers of polyurethane with poly (4,4′-diphenylsulphone terephthalamide)
Two poly (tetramethylene glycols) (PTMG), molecular weight of 650 and 2000, with 4,4′-diphenylmethane diisocyanate (MDI) and poly(4, 4′-diphenylsulphone terephthalamide) (PSA) prepolymer were polycondensated. ...

Modification of polyurethane with wholly-rigid poly (m-phenylene isophthalamide)
Flexible polyurethane (PU) was reinforced by wholly-rigid aromatic polyamide poly (m-phenylene isophthalamide) (PmlA) (Nomex) by physical polyblending and chemical copolymerization. Three polyurethane elastomers ...

Modification of nylon-6 with poly (m-phenylene isophthalamide) via MDI as a chain extender
Reinforcement of flexible nylon-6 by using poly (m-phenylene isophthalamide) PmIA (Nomex) using (MDI) 4,4′-diphenylene methane diisocyanate as a chain extender was studied. Observation by scanning electron micros...
