摘要:
An article, comprising a packaging article such as food or beverage container (20), or a portion thereof, that includes a substrate (30, 32) and a coating (34) disposed on at least a portion of the substrate (30, 32). The coating (34) is preferably formed from a coating composition that comprises a latex emulsion having a first-stage copolymer, a second-stage copolymer, and a linkage interconnecting the first-stage copolymer and the second-stage copolymer prior to curing.

A method is provided for the production and purification of monomer comprising a carboxylic betaine of Formula 2: (Formula (2)) wherein A is oxygen, methylene, ester, amide, benzyl, pyridinyl, or imidazolyl; R is hydrogen, methyl, ethyl, propyl, butyl, pentyl, hexyl; and n is an integer from 0 to 10.
摘要:
The present invention relates to a grafted pigment dispersing polymeric additive for opacifying pigments, prepared by polymerizing monomers in the presence of a polymeric pigment dispersant. The polymeric pigment dispersant has low molecular weight, high acid number and is dissolvable in alkali solution. When incorporated into paint compositions, hiding is improved with less opacifying pigments.

The present invention relates to a radically polymerizable composition comprising a hydroxylamine ester used to manufacture color filters. The invention further relates to novel hydroxylamine esters. The invention further relates to the use of hydroxylamine esters in all liquid crystal display components requiring post-baking. The present invention relates to a radically polymerizable composition comprising: (a) at least one alkaline developable resin; (b) at least one acrylate monomer; (c) at least a photoinitiator; (d) at least one hydroxylamine ester compound of formula (I) wherein R a represents an acyl radical; one of R b and R c represents hydrogen and the other one represents a substituent; or R b and R c both represent hydrogen or identical or different substituents; or R b and R c together represent oxygen; or R b and R c together form a ring; R 1 - R 4 each represent C 1 -C 6 alkyl; and R 5 and R 6 each represent independently of one another hydrogen, C 1 -C 6 alkyl or C 6 -C 10 aryl; or R 5 and R 6 together represent oxygen.
摘要:
The present invention concerns an amphiphilic polymeric material which comprises a straight or branched chain carbon-carbon backbone and a multiplicity of side chains attached to the backbone, wherein the side chains have formula (I). At least one of R 1 and R 2 is the group -C(O)Q; wherein Q comprises a hydrophilic polymeric group terminated with an amine. Chewing gum bases and chewing gum compositions comprising the amphiphilic polymeric material are provided.
摘要:
The invention relates to dental compounds that contain at least one polyacid or at least one polyacid and at least one salt of at least one polyacid. The polyacids used have at least one branch point in the polymer structure and are water-soluble and not cross-linked and their repeat units consist to at least 80 mole % of acrylic acid segments.
摘要:
Disclosed are resin-fortified emulsion resins for water-borne inks and a method for preparing the same. In preparing resin-fortified emulsion resins, a styrene/acrylic acid water-soluble resin is added in advance before the initiation of emulsion polymerization. The water-soluble resin provides the sites where the reaction can occur like conventional emulsifiers. Therefore, the emulsion resins suitable for use in water-borne inks can be obtained without using additional ionic emulsifiers. In addition, resin-fortified emulsion resins can be used in a variety of applications because of their broad ranges of acid number and glass transition temperature.
摘要:
A continuous process for making a comb-branched copolymer of an acrylic monomer and a polyether macromonomer is disclosed. The process is performed by continuously feeding a reaction zone with a monomer stream that contains an acrylic acid and a polyether macronomer, and an initiator stream. The comb-branched copolymer made thereby performs better as water reducing agent in cement compared to that made by a batch process.
