Abstract
The present invention relates to a composition comprising: (1) a polymer derived from the reaction of a polydimethylsiloxane (PDMS) (1a) having amine terminal groups –NH2 or –NHR, R being an alkyl group, preferably methyl or ethyl, with a compound (1b) having at least two isocyanate groups (-N=C=O), to obtain a polymer (1) having intrachain urea groups; (2) a polymer derived from the reaction of a polydimethylsiloxane (PDMS) (2a) having –NH2 side groups with a compound (2b) having a single isocyanate group (-N=C=O), to obtain a polymer (2) having urea side groups.
