Abstract
Polymers containing repeating units of: ##STR1## and optionally random distribution of other units derived from at least one vinyl monomer, R.sub.1 is H; alkyl, cycloalkyl or aryl each of which is unsubstituted or substituted by at least one halogen; ##STR2## (R.sub.7 is H, alkyl, cycloalkyl or aryl); A is a single bond; alkylene, cycloalkylene or arylene; or ##STR3## (B is alkylene, cycloalkylene or arylene); R.sub.2, R.sub.3 and R.sub.4 are alkyl, cycloalkyl or aryl; it being possible for at least one of R.sub.3 and R.sub.4 to contain at least one hydroxyl or carboxylic acid groups or to represent a polyoxyethylene or polyester sequence. These polymers are useful for the preparation of graft copolymers containing the units of the formula: ##STR4## where Po is a vinyl or a diene polymer sequence, and other vinyl units. These graft copolymers are useful especially as compatibility agents.
