    摘要: 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.

    摘要: A heat-curable electrocoating composition containing a polymer having pendant mercaptan groups and cross-linking agent having alpha-,beta-ethylenically unsaturated carbonyl groups can be electrodeposited onto a cathode substrate disposed within an aqueous electrocoating bath. Upon electrodeposition onto the substrate, the mercaptan groups cross-link with the alpha-,beta-ethylenically unsaturated carbonyl groups upon curing to form a fully cured electrodeposited coating on the cathode substrate.

    摘要: Addition polymers containing a plurality of terminal and/or pendant amine groups in which the nitrogen atom of at least some of such groups is of primary or secondary character, or aldimine or ketimine groups form the main film-forming component in compositions for coating and the like purposes, which also contain a polyfunctional acrylic monomer, such as ethylene glycol diacrylate, with or without monoethylenically unsaturated acrylic ester. Such compositions provide durable films having excellent mechanical and resistance properties even on ambient curing though baking may be used to accelerate the cure. A method of use is also disclosed in which the components are mixed in suitable vehicles, e.g. dispersant or solvent media, optionally with fillers and/or pigments, as desired, and after application of the composition, such as for coating, it is cured by exposure to ambient conditions, naturally occurring or controlled, or it is cured at elevated temperatures or by applying a plurality of curing conditions in succession, e.g. first to ambient conditions and subsequently to elevated temperatures in one or more stages of baking.
