4-Oxo-pyrrolidino-furoxane cpds. - useful for modifying ethylenically unsatd. polymers, esp. synthetic rubbers

摘要

New pyrrolidino-furoxans are of formula (I) (where R1 is a covalently bound organic gp.; and R11 and R111 are covalently bound (non)organic gps.) (I) are useful for modifying, esp. crosslinking, ethylenically unsatd. polymers. Mastic and caulking cpds. can be formed. The crosslinked polymers may be used in decorative or protective coatings, tyres and hoses, and have good thermal stability. Dyestuffs, antistatic agents, antioxidants and reinforcing agents can be bonded to polymers using the cpds.
