Plastic articles for medial use comprising a polymer, which polymer comprising units derived from an ethylenically unsaturated monomer having a chai n containing amino and organosiloxane groups, wherein the monomer is represented b y the following general formula: (see fig. 1) (where X is an ethylenically unsaturated polymerizable group; each R1 is, independently, selected from a hydrogen atom, unsubstituted and substituted alky l groups, unsubstituted and substituted aryl groups and the groups (CH2)rCOOR3 and (CH2)rONR4R5; each of m, n and p, independently, is selected from 0 and 1; each of q and r, independently, is any of zero and 1 to 10; and R2 is a substituent grou p containing an organosiloxane group, each of R3, R4 and R5, independently, is a g roup of R1 or is a group having a heterocyclic group, or R4 and R5, together with the nitrogen atom to which they are attached form a heterocyclic group which may additionally contain any of oxygen, nitrogen, sulfur and silicon) and further the general formula (1) satisfies one of the following features (i) to (iii), (i) n = 1 (ii) m and n are zero, and p is 1 (iii) m, n and p are zero, and R1 is other than hydrogen or methyl.
