Abstract: A carbonate compound having ethylenically unsaturated and acetylenically unsaturated functions are disclosed. The compound is represented by the formula: ##STR1## wherein, A is the residue of a hydroxy group-containing, ethylenically unsaturated monomer with removal of the hydroxyl group, R.sup.1 and R.sup.2 are independently a hydrogen atom or a C.sub.1 -C.sub.20 alkyl.

Abstract: Polymerizable carbonate compounds of the formula: ##STR1## wherein A is an aromatic polycycle, R.sup.1 and R.sup.2 are independently hydrogen atom or alkyl, and n is 1, 2 or 3, are disclosed. They are useful as a component of nonemanating, self-curing and heat resistant resin compositions.

Abstract: Crosslinked polymer microparticles are produced by emulsion polymerizing a monomer mixture containing a crosslinking monomer having a plurality of polymerizable sites in the molecule in an aqueous medium containing a polymeric amide-acid and a neutralizing base as an emulsifier/dispersant. The polymer microparticles are incorporated to thermosetting coating compositions for rheology control and other purposes. The amide-acid moieties of the emulsifier/diapersant are capable upon curing of the coating composition of cyclizing into an imide ring and the polymer amide-acid retained on the polymer microparticles, which imide moieties do not adversely affect the properties of cured films of the coating composition.

Abstract: Quaternary ammonium salts of a non-nucleophilic anion having an .alpha.-substituted benzyl group attached to the quatenary nitrogen atom or having a heterocycle including the quaternary nitrogen atom are useful as a cation polymerization initiator having a heat latency. A variety of resinous compositions containing this initiator is also disclosed.

Abstract: Polymeric polyols are prepared by reacting a polyhydroxy initiator compound with an epoxide in the presence of alkali metal hydroxide catalyst used in an amount of at least 10% by mole based on the molar amount of polyhydroxy initiator compounds. The polyols so obtained may be chain extended by reaction with further epoxide in the presence of at least 10% by mole of an alkali metal hydroxide catalyst based on the molar amount of the polymeric polyol.
