摘要:
A process for making a polyolefin composition having improved adhesive and/or coating compatibility involving: (a) providing a polyolefin; (b) providing from 0.01 to 10% by weight, based on the weight of the polyolefin, of a migratable amphiphile; (c) providing from 0.01 to 1000 ppm, based on the weight of the polyolefin, of a transition metal selected from the group consisting of titanium, tin, and mixtures thereof; and (d) combining (a)-(c) to form the polyolefin composition.
摘要:

摘要:
A process for modifying polymers containing carboxyl, hydroxyl and/or phenolic hydroxyl groups. In the process, the polymers are reacted with a delta.sup.2 mono- or bis-oxazoline, each substituted in the 2-position by an optionally substituted alkyl or alkenyl group containing from 7 to 23 carbon atoms. The modified polymers show reduced melt viscosities, lower adhesion and better slip characteristics than unmodified polymers.
摘要:
Polyolefine-based mouldings and foils contain internal bonding additives which are enriched by migration at the plastic surface and which have their molecular structure bonding substituents of higher polarity on an oleophilic hydrocarbon radical. At least one part of these internal additives is hardened via its hydrocarbon radicals in the area of the plastic surface and prevented from further migrating, and so permanent adhesive bondings and/or coatings of the polyolefine surface may be obtained without additional preliminary treatments. Also disclosed is a process for furnishing solid polyolefine surfaces with such adherence-improving, immobilised additive (mixtures), and other auxiliary agents used for that purpose.
摘要:
A polyolefin composition having enhanced dyeing capabilities containing: (a) a polyolefin; (b) from 0.01 to 10% by weight, based on the weight of the polyolefin in, of a migratable amphiphile, excluding phenolic and sulfur-containing stabilizers and n-octyl phenyl salicylate; and (c) from 0.01 to 1000 ppm of a transition metal, based on the weight of the polyolefin.

Compositions obtained by reacting the cardanol-containing raw material cashew nut shell liquid (CNSL) with (a) ammonia, or an amine which comprises at least one primary or at least two secondary amino groups, and (b) formaldehyde, are disclosed as adhesives.
摘要:
A process for producing a detergent portion, comprising the steps of forming one or more dimensionally stable hollow bodies comprising at least one compartment by injection moulding, providing one or more means for compartmentalizing the dimensionally stable hollow bodies, filling the compartment with at least one detersive formulation, and closing the compartment to form a partial or whole enclosure around the detersive formulation.
