Amphiphatic polymerizable vinyl monomers, vinyl resin particles derived from said monomers and preparation thereof

A method for preparing an amphiphatic, polymerizable vinyl monomer represented by the formula (I):

• ##STR23## wherein R.sub.1 is hydrogen or a methyl group;
• R.sub.2 is a substituted or unsubstituted aliphatic hydrocarbon having 5 to 10 carbon atoms, an alicyclic hydrocarbon having 6 to 7 carbon atoms or an aromatic hydrocarbon having 6 to 13 carbon atoms;
• R.sub.3 is a hydrocarbon residue selected from aliphatic hydrocarbons having 1 to 30 carbon atoms, alicyclic hydrocarbons having hydrocarbons having 6 to 13 carbon atoms or their substituted derivatives or a hydrocarbon residue selected from aliphatic hydrocarbons having 1 to 30 carbon atoms, alicyclic hydrocarbons having 6 to 10 carbon atoms, aromatic hydrocarbons having 6 to 13 carbon atoms or their substituted derivatives, containing in its main chain at least one group selected from a vinyl group, an allyl group, an ether group, an ester group and a carbonyl group;
• A represents ##STR24## group, in which k and l each is 0 or 1;
• D is a repeating unit of ##STR25## R.sub.4 is ethylene or propylene;
• R.sub.5 is a substituted or unsubstituted alkylene having 2 to 7 carbon atoms;
• R.sub.6 is a substituted or unsubstituted alkylene having 2 to 5 carbon atoms;
• m and n each represents an average number of the respective repeating units, wherein m is an integer of 1 to 10 and n is an integer of 2 to 50;
• and B is --COOH or --SO.sub.3 H, comprising the combination of steps of reacting an end hydroxyl bearing acrylate or methacrylate of the formula:
• ##STR26## in which R.sub.1, A and D are as defined above, with an acid anhydride of the formula:
• ##STR27## in which B and R.sub.2 are as defined above, to obtain a compound represented by the formula:
• ##STR28## and reacting the thus obtained compound (IV) with an epoxy compound of the formula:
• ##STR29## in which R.sub.3 is as defined above.
