ABSTRACT:
A resinous composition comprising an acrylic resin having end carboxyl bearing long pendant groups of the formula: ##STR1## wherein R.sub.2 is a substituted or unsubstituted aliphatic hydrocarbon having 2 to 10 carbon atoms, alicyclic hydrocarbon having 6 to 7 carbon atoms or aromatic hydrocarbon having 6 carbon atoms; A is a repeating unit of ##STR2## R.sub.3 is ethylene or propylene; R.sub.4 is a substituted or unsubstituted alkylene having 2 to 7 carbon atoms; R.sub.5 is a substituted or unsubstituted alkylene having 2 to 5 carbon atoms; m is an integer of 1 to 10; and n is an integer of 2 to 50. The invention also concerns a process for preparing said resinous composition characterizing by polymerizing a monomer mixture containing end carboxyl bearing reactive acryl monomer of the formula: ##STR3##
