First claim
Opening claim text (preview).
1 .- 25 . (canceled) 26 . A copolymer comprising: one or more polymer units M 1 selected from units of the following formulae (P-1) to (P-63); and one or more different polymer units: wherein, each * in the formulae indicates a linkage to an adjacent unit of the copolymer, and n indicates the number of units of the formula. 27 . A copolymer according to claim 26 , wherein the one or more different polymer units in the copolymer comprise at least one unit M 2 , which at each occurrence is independently selected from the group consisting of a polymerized unit derived from ethylene, propylene, an acrylate, a methacrylate and a styrene. 28 . A copolymer according to claim 26 , wherein the copolymer comprises units M 1 and M 2 in a ratio m 1 :m 2 of from 0.01 to 100. 29 . A copolymer according to claim 26 , wherein one or more polymer units M 1 and/or one or more different polymer units in the copolymer are crosslinked with each other. 30 .
