Polytetramethylene glycol PTMG

Three types of PUs were prepared, based on polytetramethylene glycol(PTMG) of molec.wt. 2000, 1000 and 650. The prepolymers were prepared by reacting PTMG with MDI and were then extended with diethylene triamine(DETA) or DETA/hydrazine mixture to form the PU polymers. The polymers were then grafted with epichlorohydrin and further reacted with different... [Pg.82]

For the synthesis of DPUR, a cycloaliphatic diisocyanate, isophorone diisocyanate (IPDI) from Fiiils, was used since unlike aromatic isocyanates, it does not result in yellowing of the coatings and films. The polyols used were polytetramethylene glycol (PTMG) with a MW of 2000... [Pg.268]

The system of polytetramethylene glycol (PTMG) of molecular weight 1000 and 4,4-diphenylmethane diisocyanate (DPMDI) was investigated. The ratio of NCO and OH groups was 1 1. Chlorobenzene was the solvent. The total concentration of the reacting substances was 0.2 mol/1. Magnesium chloride was added to the solution as a powder with the pcuticle size 5 pm. The powder was dried... [Pg.13]

SMPU is usually synthesized from long-chain polyols, diisocyanate and short-chain extenders. The polyols that have typically been used to date include polycaprolactone (PCL), polytetramethylene ether glycol (PTMG), polybutylene adipate (PBA), polyhexamethylene adipate (PHA) and polylactic acid (PLA)...
