Telechelic siloxane polymers with multiple epoxy end-groups

摘要

Telechelic polymers are presented, comprising polysiloxane polymers having multiple epoxy end-groups of the formula; $PTEXTPDATG\—R/PDATHILSPPDAT3/PDAT/SP/HILPDAT\—SiR/PDATHILSPPDAT1/PDAT/SP/HILPDATR/PDATHILSPPDAT2/PDAT/SP/HILPDATO(SiR/PDATHILSPPDAT1/PDAT/SP/HILPDATR/PDATHILSPPDAT2/PDAT/SP/HILPDATO)/PDATHILSBPDATm/PDAT/SB/HILPDATSiR/PDATHILSPPDAT1/PDAT/SP/HILPDATR/PDATHILSPPDAT2/PDAT/SP/HILPDAT\—R/PDATHILSPPDAT3/PDAT/SP/HILPDAT\—G/PDAT/PTEXT$ ;wherein each R¹ and R² are independently monovalent alkyl, alkoxy, aryl, aryloxy, and halohydrocarbon radicals having from 1 to 20 carbon atoms, halohydrocarbon radicals having the formula C_nF_2n+1CH₂CH₂— wherein n is an integer from 1 to 18; m is an integer in the range from 10 to about 1000; R³ is a divalent hydrocarbon radical having from 2 to 18 carbon atoms; and G is a silicon-based functionalized end group, wherein the functionalities are selected from the group consisting of epoxides, vinyl ethers, propenyl ether, or a combination thereof.
