âWe have an ambitious technology vision,â Weight Watchers CTO Dan Crowe said at the time of the Wello acquisition last May. âWe will become a 21st-century technology organization, engineered for the digital era, whose innovative technology fundamentally improves the way people manage their weight, health and wellness.
A fluoropolymer is a plastic material based in fluorocarbon containing carbon fluorine molecules. It is a special type of polymer that possesses special properties. The electronegative ion fluoride in a fluoropolymer gives it strong carbon-fluoride bonds, which makes it non-sticky.
Graft copolymers are a special type of branched copolymer in which the side chains are structurally distinct from the main chain. The illustration (5) depicts a special case where the main chain and side chains are composed of distinct homopolymers.owever, the individual chains of a graft copolymer may be homopolymers or copolymers. Note that different copolymer sequencing is sufficient to define a structural difference, thus an A-B diblock copolymer with A-B alternating copolymer side chains is properly called a graft copolymer.
