Abstract:
This invention relates to a polymer blend comprising: (A) about 1% by weight to about 99% by weight of at least one polymer (A) comprising terephthalic acid residues, 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues; and 1,4-cyclohexanedimethanol residues; (B) about 1 % by weight to about 99% by weight of at least one polymer (B) comprising 1, 4-cyclohexanedicarboxylic acid residues and 1,4-cyclohexanedimethanol residues, and (C) about 0.01% by weight to about 20% by weight of at least one antimicrobial agent; said weight percentages being based on the total weight of the polymer blend.
Abstract:
Polymer compositions are disclosed that are blends of polyesters prepared from terephthalic acid, 2,2,4,4-tetramethy-l,3-cyclobutanediol, and optionally 1,4- cyclohexanedimethanol, with a reinforcing mineral filler. The composition of the blend includes up to about 40 weight % of the mineral. These formulations have a combination of toughness, heat resistance, and high modulus making the materials particularly useful in engineering molding plastics.
Abstract:
Disclosed are miscible, polyester blends that contain at least one first polyester comprising terephthalic acid and 1,4-cyclohexanedimethanol, and at least one second polyester comprising terephthalic acid, 2,2,4, 4-tetramethyl-l,3-cyclobutanediol, and 1,4- cyclohexanedimethanol. The polyester blends have good clarity, toughness, and moldability and are useful for the preparation of shaped articles. Also disclosed are shaped articles prepared from the polyester blends.
Abstract:
The present invention relates to coatings for a polymer, the coating comprising a diacrylate of an aliphatic diol, a polyacrylate of an aliphatic polyol, a photoinitiator, wherein the average molecular weight between crosslinks in the coating is less than 190 g/mol. The invention further relates to articles comprising the coating and a polymer.
Abstract:
This invention relates to a blend comprising: (A) about 80% by weight to about 99.99 % by weight of at least one polyester comprising terephthalic acid residues, 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues; and 1,4-cyclohexanedimethanol residues; and (B) about 0.01 % by weight to about 20 % by weight of at least one antimicrobial agent; said weight percentages being based on the total weight of the blend.
Abstract:
Molded articles are disclosed that comprise polymer blends prepared by blending polyesters prepared from terephthalic acid, 40 to 5 mole percent 2,2,4,4-tetramethy-1,3-cyclobutanediol, and 60 to 95 mole percent 1,4- cyclohexanedimethanol, with bisphenol A polycarbonate. The composition of the blend includes up to about 95 weight percent bisphenol A polycarbonate. These blends have a combination of clarity, toughness and heat resistance making the materials particularly useful in engineering molding plastics and packaging.
Abstract:
A cellulose ester composition with heat distortion temperatures greater than 90°C is provided comprising at least one cellulose ester and optionally at least one plasticizer. The cellulose ester compositions are useful for making articles such as eyeglass frames, automotive parts, and toys are also provided.
Abstract:
This invention relates to certain poly(1,4-cyclohexylenedimethylene terephthalate) copolyesters which are useful for the preparation of clear and tough thick wall molded parts, produced at good cycle times. The copolyesters can be molded into desired shapes such as cosmetic jars, fragrance caps, tool handles, and toothbrushes. These molded articles can have thick or thin walls and may be molded in a two shot molding process. The copolyesters also have good flow and reduced cycle times.
Abstract:
Polyester blends comprising (1) polyesters prepared from terephthalic acid, 100 to 5 mol% of 2,2,4,4-tetramethyl-1,3-cyclobutanediol, and 0 to 95 mol% 1,4-cyclohexanedimethanol and (b) polyesters prepared from terephthalic acid and alkylene glycol. The blends may also contain an impact modifier and a phosphorous stabilizer. These blends can have a combination of thermal stability and toughness — making the materials useful in engineering molding plastics, packaging, films, and fibers.
