Atactic polymers such as polystyrene (PS) are technologically very important. [ citation needed ] If a special catalyst [ clarification needed ] is used in its synthesis, it is possible to obtain the syndiotactic version of this polymer, but most industrial polystyrene produced is atactic.
Atactic polypropylene has lower density, melting point and softening temperature than the crystalline types and is tacky and rubber-like at room temperature. It is a colorless, cloudy material and can be used between −15 and +120 °C. Atactic polypropylene is used as a sealant, as an insulating material for automobiles and as an additive to ...
Many English translations may not offer the full meaning of the profanity used in the context. [1] Hindustani profanities often contain references to incest and notions of honor. [2] Hindustani profanities may have origins in Persian, Arabic, Turkish or Sanskrit. [3] Hindustani profanity is used such as promoting racism, sexism or offending ...
Coordination type polymers are also stereoregular and can be isotactic or syndiotactic instead of just atactic. This tacticity introduces crystallinity in otherwise amorphous polymers. From these differences in polymerization type the distinction originates between low-density polyethylene (LDPE), high-density polyethylene (HDPE) or even ultra ...
Amorphous poly alpha olefin (APAO; also known as atactic poly alpha olefin) is a commodity chemical used in multiple applications. History In the ...

Hindustani, also known as Hindi-Urdu, like all Indo-Aryan languages, has a core base of Sanskrit-derived vocabulary, which it gained through Prakrit. [1] As such the standardized registers of the Hindustani language (Hindi-Urdu) share a common vocabulary, especially on the colloquial level. [ 2 ]
Hindustani is extremely rich in complex verbs formed by the combinations of noun/adjective and a verb. Complex verbs are of two types: transitive and intransitive. [3]The transitive verbs are obtained by combining nouns/adjectives with verbs such as karnā 'to do', lenā 'to take', denā 'to give', jītnā 'to win' etc.
