摘要： The present invention provides compositions of phosphorus acid group and methacrylic anhydride group containing telomeric copolymers of methacrylic acid having an as yet never achieved amount of more than 70 wt. %, or, preferably, 72 wt. % or more, and up to 99 wt. %, of methacrylic anhydride groups based on the total weight of polymerized methacrylic acid and/or salt units. The compositions enjoy higher thermal stability than was previously achieved and enable easer processing that does not require the removal of liquids or solvents.

摘要： The present invention provides fiber cement articles, such as roof tiles having improved impact and hail resistance and methods for making them. The fiber cement articles comprise cement, an optional filler, reinforcing fibers, such as poly(vinyl alcohol) fibers or a mixture of cellulosic and synthetic fibers, one or more core-shell aqueous emulsion polymers having a crosslinked rubbery core with a calculated glass transition temperature (calculated Tg) of from −20 to −140° C., and an at least partially grafted acrylic or vinyl shell polymer having a calculated Tg of from 20 to 170° C., and having a Z-average primary particle size of from 55 to 800 nm, or, preferably, from 140 to 650 nm. The solids weight ratio of the crosslinked rubbery core to the shell of the core-shell aqueous emulsion polymer may range from 85:20 to 97:3.

摘要： The present invention provides polymer compositions of one or more phosphorus acid group containing, polymers of six-membered cyclic methacrylic acid imide comprising a backbone polymer having one or more one methacrylic acid in polymerized form or its salt, quaternary ammonium group, ester side chain group or amide side chain group, wherein the backbone polymers comprise from 60 to 100 wt. %, based on the total weight of monomers used to make the backbone polymer, of total methacrylic acid polymerized units, regardless of their form, and wherein a total of from 7.5 to 95 wt. %, or, preferably, less than 70 wt. % of the methacrylic acid polymerized units comprise methacrylic anhydride groups or six-membered cyclic methacrylic imide groups. The polymer can be readily tailored to boost modulus and modify surface energies when added to polymers like polyolefins, and to make them compatible with other polymers, like polyamide.

摘要： The present disclosure provides for a coating formulation that includes a pigment, an organic aqueous emulsion and an organophosphonic acid of the formula: where R is a saturated or unsaturated alkyl having 2 to 10 carbon atoms or a substituted or unsubstituted aryl having 5 to 10 carbon atoms. The coating formulation can be used in forming a topcoat in an exterior insulation and finish system (EIFS). The present disclosure also provides for a method of forming a topcoat on a surface of the EIFS that helps to protect the underlayment of the EIFS against both weathering and moisture while helping to maintain color retention.
