1. A composition comprising:
(a) a biologically compatible structural component comprising a linear acrylic homopolymer or a linear acrylic copolymer; and (b) a biobeneficial component comprising a copolymer having an acrylate moiety and a biobeneficial moiety;wherein the copolymer composing the biobeneficial component has the formula: wherein (a) m1, n1, p1, r1, m2, n2, p2, and r2 are all integers; (b) m1≧0, n1>0, p1≧0, r1>0; m2≧0, n2>0, p2≧0, r2>0; and (c)
(i) if m1=0, then p1>0;(ii) if p1=0, then m1>0; and(iii) if m2=0, then p2 >0; and(iv) if p2=0, then m2>0; and(v) r1 and r2 are the same or different;(vi) m1 and m2 are the same or different;(vii) n1 and n2 are the same or different; and(viii) p1 and p2 are the same or different; (d) X is hydrogen or methyl group; (e) each of R, R1 and R2, independently, is methyl, ethyl, n-propyl, iso-propyl, n-butyl, sec-butyl, iso-butyl, tert-butyl, lauryl, or 2-hydroxyethyl; and (f) Q is a fragment providing the copolymer with biobeneficial or bioactive properties. |
