Abstract: Copolymer substantially free from compositional drift can be produced in a batch-type addition copolymerization process to a high degree of conversion by initiating the reaction in a monomer-containing phase (optionally dispersed in another phase of a reaction mixture) containing the monomers at mole ratios f.sub.i such that the monomers will initially be incorporated into copolymer at the desired mole ratios F.sub.i and sustaining the reaction while simultaneously controlling the addition each monomer to the phase in which the copolymerization reaction is continuing according to the relationQ.sub.i = f.sub.i Q.sub.0 + (F.sub.i - f.sub.i Q.sub.0 /Q.sub..infin.)Z,where Q.sub.i is the running cumulative moles of monomer i added to the phase in which reaction is occurring (including that initially present), Q.sub.0 is the total moles of all monomers initially present in that phase, Q.sub..infin.

Abstract: Lower hydroxyalkyl amines in which at least one of the amino hydrogens is replaced by an acyclic monoterpenyl radical or hydrogenated acyclic terpenyl radical are useful repellents for insect repelling compositions.

Abstract: Growth of fungi can be controlled by applying to the fungi a fungicidal composition comprising an effective quantity of a cyanoalkyl sulfonate of the formula ##EQU1## wherein R.sub.1 is an alkylene group having from 1 to 4 carbon atoms and R is an aryl or arylalkyl group or an aliphatic group comprising a 1 to 12 carbon atom alkyl or cycloalkyl group at the site of attachment.

Abstract: Advantageously controlled paint film flow during curing of the film at elevated temperature for avoidance of inadequately coated areas is obtained in an electrocoating operation of an electrode workpiece employing as paint vehicle a mixture of electrodepositable resin and water-dispersible aminoplast or phenoplast resin crosslinkable therewith by incorporating into said vehicle, or into the bath containing same, a small proportion of curing accelerator acid such as a sulfonic acid which is codepositable with said paint film in concentration sufficient for yielding a substantially continuous cured film on the resulting coated substrate. The degree of cure of the deposited coating is monitored by monitoring a property of cured coating which is a function of the degree of cure, and the concentration of the curing accelerator in the bath is adjusted in response thereto to maintain the monitored property at a predetermined value.
