The invention relates to the use, in emulsion polymerization, of at least a compound derived from a terpene and comprising a number of oxypropylene units ranging between 0 to 20, and a number of oxyethylene units ranging between 2 to 80.

Use of polyoxypropylene and polyoxyethylene terpene compounds in emulsion polymerization

The invention concerns polyalkoxylated terpenic compounds of formula Z-X&#x2014;W&#x2014;[CH(R)&#x2014;CH(R)&#x2014;O]-A in which Z is a bicycloheptenyl or bicycloheptyl radical, preferably substituted by methy radicals; X is preferably a &#x2014;CH&#x2014;CH&#x2014;O or O&#x2014;CH&#x2014;CH&#x2014;O&#x2014; radical; W is a polysequence, preferably polyoxypropylene and polyoxyethylene; [CH(R)&#x2014;CH(R)&#x2014;O]is a sequence different from a polyoxyethylene sequence, preferably polyoxypropylene; A is H, a functional or hydrocarbon group. They can be prepared by successively polyalcoxylating the reagent Z-XH. They can be used as antifoaming agents in foaming aqueous media, in particular in degreasing aqueous media in alkaline medium of sheet metals, as well as detergent aqueous media in household washing or industrial and institutional washing.

The invention concerns a composition for stripping coatings for example of paints. Said composition comprises at least an aromatic ether containing an alkoxy group with at least two carbon atoms and at least an aprotic polar solvent.

Paint stripping composition

The present invention relates to a process for removing fatty substances. According to this process, the following steps are carried out:1) at least a first degreasing operation is carried out on the article to be treated, in the presence of a solvent mixture comprising at least one compound (a) chosen from C,-C,dialkyl esters of at least one C,-C,aliphatic diacid, and at least one compound (b) which is miscible in the compound (a) and which at least partially dissolves the fatty substance contaminating the article, 2) at least a second degreasing operation is optionally carried out, in the presence of a solvent mixture comprising at least one compound (a) and at least one compound (b) as defined above, with a compound (a)/compound (b) volume ratio of greater than or equal to 1, 3) a third degreasing operation is carried out in the presence of compound (a), 4) the article thus treated is rinsed with water.
