Claim:
A polymerization process, comprising initiating polymerization with an O-Imino-isourea compound of formula (I) wherein: n is 1, 2, 3 or 4; R 100 and R 101 are independently H, C 1-18 alkyl, C 3 -C 12 cycloalkyl, C 6 -C 14 aryl, C 1 -C 14 heteroaryl, C 7 -C 15 aralkyl, C 2 -C 14 heteroaralkyl, Cyano, or R 100 and R 101 form together with a carbon to which they are attached a mono or polycyclic C 3 -C 18 carbocyclic or C 1 -C 18 heterocyclic ring; R 102 and R 103 are independently C 1 -C 18 alkyl, C 3 -C 12 cycloalkyl, C 6 -C 14 aryl, C 6 -C 14 aryl substituted with at least one C 1 -C 18 alkyl, C 7 -C 15 aralkyl, (CH 3 ) 3 Si—, or R 102 and R 103 are C 1 -C 18 alkyl, C 3 -C 12 cycloalkyl, C 6 -C 14 aryl, C 7 -C 15 aralkyl, or R 102 and R 103 are C 1 -C 18 alkyl, C 3 -C 12 cycloalkyl which are interrupted or substituted by O or by N containing groups selected from the group consisting of C 1 -C 18 alkylamino, bis(C 1 -C 18 alkyl)amino, and tris(C 1 -C 1t alkyl)ammonium; R 104 if n is 1 is H, C 1 -C 18 alkyl, C 3 -C 12 cycloalkyl, C 7 -C 14 aralkyl, C 6 -C 14 aryl or an acyl selected from the group consisting of —C(═O)—H, —C(═O)—C 1 -C 18 alkyl, —C(═O)—C 2 -C 18 alkenyl, —C(═O)—C 6 -C 14 aryl, —C(═O)—C 2 -C 18 alkenyl-C 6 -C 14 aryl, —C(═O)—O—C 1 -C 18 alkyl, —C(═O)—O—C 6 -C 14 aryl, —C(═O)—NH—C 1 -C 18 alkyl, —C(═O)—NH—C 6 -C 14 aryl and —C(═O)—N(C 1 -C 18 alkyl) 2 ; or R 102 and R 104 if n is 1 form together with a nitrogen atom to which they are attached a 5 to 12 membered ring which optionally comprises an additional heteroatom; R 104 if n is more than 1 is di-, tri-, tetra-C 1 -C 18 alkylidene, di-, tri- or a tetraacyl, and salts thereof.
