| The original results in production of isotactic and stereoblock type polypropylenes are presented. |
|
| Nor have we found crystalline isotactic poly reported elsewhere in the literature. |
|
| Best known for his work in polymer chemistry, Vandenberg independently discovered isotactic polypropylene. |
|
| We recently reported the retardation of the rate of crystallization, measured calorimetrically, in isotactic polystyrene nucleated with silica. |
|
| The polymer repeating unit has the following structure: Only the isotactic form of polypropylene is marketed in significant quantities. |
|
| This extremely desirable structure owes its elasticity to the isotactic nature of the polymer, and for this reason these polymers are used for the manufacturing of car tires. |
|
| In this paper, we turn our attention to grafting methyl methacrylate onto isotactic polypropylene. |
|
| A fibrillated isotactic polypropylene three-dimensional plexifilamentary fiber, characterized in that a microwave birefringence of said three-dimensional plexifilamentary fiber is 0.07 or more. |
|
| To produce a rubbery polypropylene, a catalyst can be made which yields isotactic polypropylene, but with the organic groups that influence tacticity held in place by a relatively weak bond. |
|
| The placement of the propylene residues is predominantly in a stereoregular isotactic manner. |
|
| We used commercial isotactic polypropylene Basel Moplen HP456J as a matrix material. |
|
| Most commercial PP is isotactic with all methyl groups orientated on the same side of the backbone of the polymer chain. |
|
| In contrast, an isotactic stereoblock polymer has a higher melting point. |
|
| By far the most common thermoplastic and rubber phases applied in TPVs are, respectively, isotactic polypropylene and ethylene-propylene-diene monomer rubber. |
|
| Isotactic polypropylene is a widely used thermoplastic polymer owing to its low cost and good comprehensive properties. |
|
| Isotactic polypropylene is one of the most widely used commercial polymers owing to its good performance-to-price ratio. |
