Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
97 words
A METHOD OF ADHERING A FABRIC CORD TO AN ELEMENT OF VULCANIZABLE ISOOLEFIN-DIOLEFIN RUBBERY COPOLYMER COMPRISING THE STEPS OF DIPPING SAID CORD IN AN AQUEOUS SOLUTION COMPRISED OF A MIXTURE OF A PHENOL-ALDEHYDE RESIN WITH A BUTADIENE STYRENE-VINYL PYRIDINE LATEX, DRYING THE CORD, DIPPING THE DRY CORD IN A SOLUTION OF A BROMINATED RUBBERY COPOLYMER OF ISOBUTYLENE AND ISOPRENE HAVINGG A BROMINE CONTENT OF FROM 5 TO 30% BY WEIGHT BASED ON THE WEIGHT OF BROMINATED COPOLYMER BEFORE BROMINATION, AGAIN DRYING THE CORD, AND HOLDING SAID CORD AGAINST SAID RUBBERY ELEMENT WHILE APPLYING VULCANIZING HEAT AND PRESSURE.
