Star polymers having multiple polyisobutylene arms emanating from a calixarene core, initiators therefor, and method for the synthesis thereof

DETAILED DESCRIPTION What is claimed is: 1.
A composition of matter comprising: a core component selected from the group consisting of a p-methoxy cumyl group and a calix?n!arene where n=4 to 16; and N number of arms of polyisobutylene connected to said core component, where N=1 when said core component is said p-methoxy cumyl group and N=n, when said core component is said calix?n!arene, and wherein said composition is directly telechelic.
2.
A composition of matter as set forth in claim 1, wherein said core component is a calix?n!arene where n=6 to 16.
3.
A composition of matter as set forth in claim 2, wherein said core component is a calix?8!arene.
4.
A composition of matter as set forth in claim 1, wherein each said polyisobutylene arm has a functionalized tert-Cl group at the end thereof.
5.
A composition of matter as set forth in claim 4, wherein the composition can be further functionalized based upon dehydrochlorination or substitution of said tert-Cl group.
6.
A composition of matter as set forth in claim 1, wherein said composition has a polydispersity of less than 1.
4.
7.
A composition of matter as set forth in claim 1, wherein said composition has a polydispersity between 1.
1 and 1.
15.
8.
A viscosity modifier comprising the composition of claim 1.
9.
A composition of matter suitable for use as a cationic polymerization initiator having the structure ##STR18## wherein R is selected from the group --OCH3, --OH, and --Cl and wherein y=1 and n=4 to 16.
10.
A composition of matter as set forth in claim 9, wherein n=6 to 16.
11.
A composition of matter as set forth in claim 9, wherein n=8 and the composition is selected from the group consisting of the tert-methoxy, tert-hydroxy, and tert-Cl derivatives of 5,11,17,23,29,35,41,47-octaacetyl-49,50,51,52,53,54,55,56-octamethoxycalix ?8!arene.
12.
