Title:
HYPERBRANCHED FLUOROELASTOMER ADDITIVE
Document Type and Number:
WIPO Patent Application WO/2012/168351
Kind Code:
A1
Abstract:
The invention pertains to a hyperbranched (per)fluoroelastomer [fluoroelastomer (B)] comprising recurring units derived from a bis-olefin [bis-olefin (OF)] having general formula (I): wherein R1, R2, R3, R4, R5 and R6, equal or different from each other, are H or C1 -C5 alkyl; Z is a linear or branched C1-C18 alkylene or cycloalkylene radical, optionally containing oxygen atoms, preferably at least partially fluorinated, or a (per)fluoropolyoxyalkylene radical, said fluoroelastomer (B) having a slope in G' curve such that the ratio: G'100/G'0.01 is of less than 10, when determined at 260°C according to ASTM D4440 standard, wherein G'100 is the storage modulus at a shear rate of 100 rad/sec and G'0.01 is the storage modulus at a shear rate of 0.01 rad/sec, to compositions comprising the same, and to a process for their manufacture.
